  • How does it feel?

    Shankapushpi tastes bitter, pungent and astringent with a sweet post digestive effect. 

    Shankapushpi has a cooling effect, bringing both nourishing oiliness and lightness to the head region due to its unctuous quality and balancing effect.

  • Into the heart of shankapushpi

    Shankapushpi (Evolvulus alsinoides)
    Shankapushpi (Evolvulus alsinoides)

    The plant has shown a wide range of pharmacological activities such as antioxidant, antiamnesic (reduces memory loss or cognitive impairment), anticonvulsant, antidepressant, immunomodulatory, anti-inflammatory, antidiabetic, antihypertensive and antimicrobial activities (4).

    The primary bioactive compound, scopoletin, a furanocoumarin with well researched neuroprotective, anticholinesterase, and anxiolytic properties. Research has shown that scopoletin inhibits acetylcholinesterase, which may help increase levels of acetylcholine, a neurotransmitter responsible for learning and memory. This mechanism is targeted by pharmaceutical drugs used in Alzheimer’s (5). Additional constituents include beta-sitosterol, kaempferol, phyllanthin, and various alkaloids that collectively contribute to the herb’s multi-mechanism action on the central nervous system.

    From an energetic perspective, its astringency helps to curb bleeding in the food, urinary and reproductive channels recognised in Ayurveda. Its bitter and pungent taste improves appetite and digestion. Its sweet and flowing quality encourages the bowel to function effectively . Its blood purifying and pitta pacifying action make it useful in many skin diseases. Its unctuous quality and sweet post digestive action supports its use as a reproductive tonic  (6). The fact that it is also tridoshic, balancing all three dosha recognised in Ayurveda, also makes it widely supportive.

  • What practitioners say

    Nervous systemNervous system

    Shankapushpi goes directly to the nervous tissue and treats pain, anxiety, insomnia, epilepsy and convulsions. It enters the channel of the mind, alleviates stress and promotes the integrity of the nervous system. Its descending nature draws the rising vata downwards and helps to clean all the tissues (Bhavaprakasa). Can be combined with vacha (Acorus calamus), brahmi (Bacopa monnieri), kushtha (Saussurea lappa) in epilepsy, nerve conditions; also useful in speech impediment and to improve memory).

    Digestive system

    Useful with slow digestion, water retention, borborygmus and constipation. It is specifically beneficial where digestion is upset by nervousness and anxiety. Its sweet and flowing quality encourages the bowel to also flow freely. Can be combined with gokshura (Tribulus terrestris), coriander (Coriandrum sativum) and fennel (Foeniculum vulgare) for digestive gurgling and swelling.

    Cardiovascular system

    Its astringency is useful for stopping bleeding in the intestines, urinary and reproductive system, especially when combined with manjishtha (Rubia cordifolia) and amalaki (Phyllanthus emblica).

    Reproductive system

    Its affinity for the deeper tissues and the reproductive tissue is used to promote fertility in both men and women (Bhavaprakasa). Best combined with herbs such as ashwagandha (Withania somnifera), shatavari (Asparagus racemosus) and kapikacchu (Mucuna pruriens).

    Skin health

    It has a useful alterative function on the blood tissue and benefits skin diseases with a nervous component. One can combine with gotu kola (Centella asiatica), manjishtha, neem (Azadirachta indica) in skin disorders (6,8).

  • Shankapushpi research

    Shankapushpi (Evolvulus alsinoides)
    Shankapushpi (Evolvulus alsinoides)

    While modern pharmaceuticals have historically relied on animal testing to ensure safety and efficacy — a requirement in the approval process of novel therapeutic agents for human use — Herbal Reality does not endorse nor support animal testing when determining the efficacy of time-tested natural herbal ingredients. Our stance is aligned with ethical frameworks that strive to reduce, refine, and replace animal experiments, emphasising the importance of welfare and continual pursuit of innovative, non-animal-based testing methods

    Research on Evolvulus alsinoides in humans remains predominantly observational and case-based and large randomised controlled trials are unfortunately lacking, despite its potential.

    Review on Evolvulus alsinoides and a brief outlook into the neuroprotective activity of Convolvulaceae plants

    A 2021 review of Evolvulus alsinoides reinforces why it is widely recognised in Ayurveda for its cognitive-enhancing, antiepileptic and immune-supporting effects. The Convolvulaceae family includes approximately 1,600–1,700 species, many of which have demonstrated beneficial effects on the central nervous system (CNS). Research on E. alsinoides has identified numerous pharmacological properties, including antioxidant, memory-enhancing, anticonvulsant, antidepressant, anti-inflammatory, antidiabetic, antihypertensive, antimicrobial and immunomodulatory activities.

    This review examines the plant’s morphology, phytochemical composition and therapeutic potential, while also summarising evidence for neuroprotective and antiamnesic effects among related Convolvulaceae species. Although existing studies suggest significant promise for improving CNS function, further detailed research and clinical trials are necessary to fully establish the therapeutic efficacy of this plant family (4).

    Neuropharmacological evaluation on four traditional herbs used as nervine tonic and commonly available as Shankhpushpi in India

    Shankhpushpi is attributed to four different plants, but comparative evaluation shows that Evolvulus alsinoides stands out: among the four candidate species in this 2018 review. E. alsinoides and Canscora decussata offered the strongest protection against β-amyloid neurotoxicity, while E. alsinoides was clearly superior in antioxidant capacity, AChE inhibition, and LOX inhibition. It also produced the most robust improvements in scopolamine-induced memory deficits in water maze tests, outperforming Clitorea ternatea and Convolvulus pluricaulis.

    These enhanced neuropharmacological effects are linked to its richer profile of steroids (stigmasterol, betulinic acid), coumarins (scopoletin), and flavonoids (β-carotene, chlorogenic acid). This review helps position E. alsinoides as the most promising shankhpushpi candidate for developing interventions for neurodegenerative and cognitive disorders, including Alzheimer’s disease (3).

    Safety evaluation of sankhaholi (Evolvulus alsinoides Linn.) in the management of essential hypertension: A randomized standard control trial

    In a six-week randomised controlled Unani clinical trial, 41 adults with stage-one essential hypertension were treated either with powdered Evolvulus alsinoides at a dose of 3 g twice daily (6 g/day total) or standard ramipril therapy to evaluate safety and therapeutic effects.

    The study found that participants receiving Evolvulus alsinoides showed no significant adverse clinical effects and laboratory monitoring—(including complete blood count, liver function, and kidney function tests) remained stable throughout treatment, suggesting good short-term tolerability at this dosage. While the herb demonstrated potential antihypertensive benefits within the traditional medicine framework, the primary strength of the study was its support for short-term safety rather than definitive efficacy, with limitations including small sample size and lack of long-term follow-up (9).

    A clinical study on the management of anxiety neurosis with Sankhaholi

    In a 2007 single-blind, randomised, placebo-controlled clinical trial of 60 adults aged 18–50 with generalized anxiety disorder were treated with Evolvulus alsinoides powder at 3 g nightly or placebo for six weeks. Participants showed a substantial reduction while the placebo group showed essentially no meaningful improvement.

    The herb significantly improved a broad range of anxiety symptoms including tension, insomnia, cardiovascular complaints, and cognitive symptoms, without notable adverse effects, sedation, withdrawal symptoms, or laboratory toxicity.

    The authors concluded it demonstrated promising anxiolytic efficacy and good short-term tolerability, suggesting potential as a traditional herbal treatment for anxiety, though the study’s limitations (single-blind design, modest sample size, and limited modern methodological rigor) mean larger, more rigorous trials are still needed (10).

    In vitro propagation and cell cultures of memory tonic herb Evolvulus alsinoides: A best source for elicited production of scopoletin

    Evolvulus alsinoides, the classical source of shankhapushpi, can be efficiently micro-propagated and used to significantly boost scopoletin production up to 75-fold through optimised plant tissue culture and specific biochemical enhancers. The study used an in vitro culture system to ensure optimal plant shoot regeneration, while biochemical elicitors such as L-arginine, sodium pyruvate and yeast extract boosted scopoletin levels by 75-fold, 72-fold and 58-fold, respectively.

    These act as elicitors, stimulating secondary metabolite pathways. The work establishes a scalable platform for producing scopoletin, supporting future development of standardised herbal formulations and potential pharmaceutical applications (11).

    Neuroprotective activity of Evolvulus alsinoides and Centella asiatica ethanolic extracts in scopolamine-induced amnesia in Swiss albino mice

    A 2019 study compared E. alsinoides with Centella asiatica in scopolamine-induced amnesia in Swiss albino mice. Both showed significant neuroprotective activity, but E. alsinoides demonstrated superior performance in inhibiting acetylcholinesterase activity (12).  A similar 2010 study looked at its effects on learning and memory in rodents finding it showed clear nootropic effects. (13).

    A 2012 in vitro and in vivo study  using a streptozotocin-induced model of Alzheimer’s disease collectively supports its role as a multi-target cognitive enhancer with promising relevance for neurodegenerative disorders (14).

  • Historical use of shankapushpi

    Shankapushpi (Evolvulus alsinoides)
    Shankapushpi (Evolvulus alsinoides)

    Shankhapushpi has been used since ancient times in Ayurvedic texts, with references dating back over 2,000 years, and is recognised for its calming effects on the mind. Ayurvedic texts classify it as a medhya rasayana, a herb that specifically rejuvenates intellect and memory. It has a place alongside brahmi (Bacopa monnieri), mandukaparni (gotu kola, Centella asiatica), and vacha (sweet flag, Acorus calamus) in the list of four primary brain tonics.

    Indeed, Ayurveda considers shankapushpi as one of the best sedatives, excellent for calming mental and emotional disorders, relieving pain, anxiety, insomnia and convulsions. It enters the mind channel and  has affinity with the nerve tissue.

    Classical Ayurvedic texts describe several ways to use this herb. The most celebrated is as a fresh juice, which Charaka recommends as the finest mode of medhya rasayana administration (7). It rebalances one of the five sub-types of vata dosha and apana vata, improves digestion and elimination; and is used for stress related digestive problems, flatulence, bloating, colic and constipation.

    It is also an excellent tonic to promote fertility. It clears ama (undigested matter) from the blood tissue hence it clears the skin, especially in stress related skin problems. It also reduces cholesterol and improves symptoms of hyperthyroidism. Overall, shankapushpi is valued for its potential to improve mental clarity and emotional stability, making it a significant herb in Ayurvedic medicine. Externally, it is also used as a paste for skin diseases as well as in siddha oil for encouraging hair growth (2).

  • Shankapushpi’s herbal actions

    Herbal actions describe therapeutic changes that occur in the body in response to taking a herb. These actions are used to express how a herb physiologically influences cells, tissues, organs or systems. Clinical observations are traditionally what have defined these actions: an increase in urine output, diuretic; improved wound healing, vulnerary; or a reduction in fever, antipyretic. These descriptors too have become a means to group herbs by their effects on the body — herbs with a nervine action have become the nervines, herbs with a bitter action are the bitters. Recognising herbs as members of these groups provides a preliminary familiarity with their mechanisms from which to then develop an understanding of their affinities and nuance and discern their clinical significance.

  • Shankapushpi’s energetic qualities

    Herbal energetics are the descriptions Herbalists have given to plants, mushrooms, lichens, foods, and some minerals based on the direct experience of how they taste, feel, and work in the body. All traditional health systems use these principles to explain how the environment we live in and absorb, impacts our health. Find out more about traditional energetic actions in our article “An introduction to herbal energetics“.

  • What can I use shankapushpi for?

    Shankapushpi (Evolvulus alsinoides)
    Shankapushpi (Evolvulus alsinoides)

    Evolvulus alsinoides (commonly known as shankhapushpi, sangapoo or sankhaholi in some regions) is used across multiple traditional medical systems, most prominently in Ayurveda, where it is classified as a medhya rasayana for supporting memory, cognition and mental clarity. It also appears in Unani medicine as a nervine and cardiac/cerebral tonic and in Siddha traditions of South India where it is used for nervous system disorders, epilepsy, and general debility. In folk medicine across India, Southeast Asia and parts of Africa, it is additionally used for anxiety, fever, respiratory complaints, and overall strengthening purposes (1).

    Shankhapushpi is primarily used in Ayurveda for its memory-enhancing and anxiolytic properties. It is believed to improve cognitive function and is often used in brain tonic formulations, which rejuvenate and enhance cognition and memory and is recommended for students in the form of a syrup to help during exam season. It also treats anxiety, cognitive impairment and epilepsy.

    Beyond supporting the nervous system, it has applications for improving digestion and elimination, especially with any stress-related digestive issues, flatulence, bloating, colic and constipation. It is also used in bleeding disorders, as a reproductive tonic and for hyperthyroidism. It can help reduce skin blemishes such as acne, especially when this is stress related (2).

    There is confusion around the name  ‘shankhapushpi’ which has led to this herb being less known than it should be. The Ayurvedic name shankhapushpi is used for at least three different species: Evolvulus alsinoides, Convolvulus pluricaulis, and Clitorea ternatea (4).  Different regional traditions in India and commercially available products hence use different botanical sources. When research reviews amalgamate all three together, the individual benefits of each individual species becomes challenging to assess.

  • Did you know?

    The exact species of shankapushpi is used interchangeably around India with three species being known by the same Sanskrit name — Convolvulus pluricaulis, Clitoria ternata and Evolvus alsinoides. Although these different species are used interchangeably for their nervine properties, they do not necessarily compare with regard to their actions. However, all these species have a profound impact on the nervous system (8).

  • Botanical description

    Identification of authentic Evolvulus alsinoides is vital because commercial Shankhpushpi products are often adulterated or substituted, and correct identification protects both efficacy and safety. However, the exact species of shankapushpi is used interchangeably around India.

    In the classical text Bhavaprakash, shankapushpi is classified as Convolvulus pluricaulis (15), as it is in the Ayurvedic Formulary of India (16). Evolvus alsinoides is listed in Indian Medicinal plans as shankapushpi. Clitoria ternatea is used in south India for shankapushpi.

    True E. alsinoides is a small, low-growing herb (20–40 cm) with hairy, oval leaves and bright blue or white, five-petalled funnel-shaped flowers that appear singly in the leaf axils, not in clusters. This solitary flowering pattern clearly distinguishes it from Convolvulus pluricaulis, which has larger, pink-tinged flowers and a different growth habit (16).

    It is a perennial herb with numerous stems, prostrate or ascending, with slender spreading hairs. It can be found growing in woodlands, grasslands, savanna, edges of thickets, roadsides and sandy soils  of cultivated land. It is found mostly in more or less open savannah and thorn veld. It can also occur as a weed in waste places and arable or pastoral land (17).

  • Common names

    • Sankhini
    • Aloe weed
    • Bindweed
    • Dwarf morning glory
  • Habitat

    Evolvulus alsinoides is a low-growing, sun-loving plant that thrives in warm tropical to subtropical climates. Shankapushpi is primarily wild harvested for its medicinal uses. The native range of this species is tropics and  subtropics. It is an annual or perennial and grows primarily in the subtropical biome. It is found as a small creeper growing all over wasteland in India (16).

  • How to grow shankapushpi

    Shankapushpi performs best in full, direct sunlight and prefers moderate temperatures around 25°C, making it suitable for warm outdoor environments or containers in frost-free zones. It grows best in well-draining loamy soil, which should be kept slightly moist but never waterlogged. Good drainage is essential to prevent root rot, so sandy or loose soil mixes are ideal. Overall, it is a low-maintenance, hardy ground-cover plant that prefers sun, warmth and well-drained soil, with minimal but consistent care.

    • Water the plant regularly, allowing the top layer of soil to dry slightly between watering sessions. It does not tolerate constant soggy conditions but also should not be left completely dry for long periods.
    • A balanced fertiliser can be applied every 4–6 weeks during the growing season to support healthy growth and flowering.
    • Propagation is simple and can be done using seeds or stem cuttings. Seeds should be sown in moist, well-draining soil, while cuttings root best in warm, bright conditions with consistent moisture.
    • Light pruning helps maintain a compact, bushy shape and encourages denser growth, especially in spring or early summer.
  • Herbal preparation of shankapushpi

    • Powder: Dried whole plant used internally 
    • Fresh juice: Used for stronger therapeutic effect 
    • Decoctions: Fresh or dried herb boiled in water until reduced

  • Safety

    The herb is generally considered safe at traditional doses but has not been evaluated for safety in pregnancy, lactation or paediatric populations in modern clinical trials (1). 

    A clinical Unani trial involving giving 3 g twice daily (6 g/day) for six weeks showed no major safety parameter changes in adults with stage-one hypertension (9).

    A clinical study on the management of anxiety neurosis showed no notable adverse effects, sedation, or withdrawal symptoms (10).

  • Interactions

    The best current evidence for interactions involving Evolvulus alsinoides is not a dedicated human interaction trial, but rather broader pharmacology reviews plus species-specific monographs that evaluate theoretical and preclinical interaction potential.

    For example, this comprehensive species review summarises CNS, cardiovascular and metabolic effects and notes sedative, anxiolytic, and antihypertensive actions that may create interaction risks (1).

    Caution is needed with sedative medications and other CNS depressants (e.g., alcohol, opiates, benzodiazepines, anaesthetics, tricyclic anti-depressants, anti-epileptics) (2). 

  • Contraindications

    Because shankapushpi demonstrates measurable blood-pressure-lowering effects in hypertensive adults, herbal safety reviews generally advise caution in people with naturally low blood pressure, those prone to dizziness/syncope and patients taking antihypertensive drugs (9). 

    Caution is advised with use in people with hypothyroidism due to its potential thyroid suppressive effects (2).

  • Sustainability status of shankapushpi

    While Evolvulus alsinoides is not universally classified as critically endangered, unsustainable wild harvesting, habitat degradation, and commercial misidentification pose meaningful long-term ecological risks. It also shows poor seed viability, seasonal growth limitations, and destructive uprooting by traditional harvesters, all of which create conservation pressure and support the need for micropropagation and cultivation strategies (20). Cultivation, botanical standardisation, accurate species authentication and regulated sourcing are key to preserving both medicinal quality and environmental sustainability (21). 

    Read our article on Herbal quality and safety: What to know before you buy and Sustainable sourcing of herbs to learn more about what to look for and questions to ask suppliers about sustainability.

  • Quality control

    Shankapushpi is traditionally collected from wild populations and increased commercial demand for cognitive and adaptogenic herbs may lead to adulteration and contamination, especially considering the extensive confusion around what is classed as ‘shankhapushpi’ which may refer to multiple species: Evolvulus alsinoides, Convolvulus pluricaulis, Clitoria ternatea  and Canscora decussata. Research shows there is market adulteration, name confusion, substitution with spurious species and a need for microscopy, HPTLC, and phytochemical fingerprinting (4,22,).

Aromatic
An ‘aromatic’ remedy, high in volatile essential oils, was most often associated with calming and sometimes ‘warming’ the digestion. Most kitchen spices and herbs have this quality: they were used both as flavouring and to ease the digestion of sometimes challenging pre-industrial foods. Many aromatics are classed as ‘carminatives’ and are used to reduce colic, bloating and agitated digestion. They also often feature in respiratory remedies for colds, chest and other airway infections. They are also classic calming inhalants and massage oils, and are the basis of aromatherapy for their mental benefits.
Astringent
The astringent taste you get with many plants (the most familiar is black tea after being stewed too long, or some red wines) is produced by complex polyphenols such as tannins. Tannins are used in concentrated form (e.g. from oak bark) to make leather from animal skins. The process of ‘tanning’ involves the coagulation of relatively fluid proteins in living tissues into tight clotted fibres (similar to the process of boiling an egg). Tannins in effect turn exposed surfaces on the body into leather. In the case of the lining of mouth and upper digestive tract this is only temporary as new mucosa are replenished, but in the meantime can calm inflamed or irritated surfaces. In the case of open wounds tannins can be a life-saver – when strong (as in the bark of broadleaved trees) they can seal a damaged surface. One group of tannins, the reddish-brown ‘condensed tannins’ are procyanidins, which can reduce inflammation and oxidative damage.
Bitter
Bitters are a very complex group of phytochemicals that stimulate the bitter receptors in the mouth. They were some of the most valuable remedies in ancient medicine. They were experienced as stimulating appetite and switching on a wide range of key digestive functions, including increasing bile clearance from the liver (as bile is a key factor in bowel health this can be translated into improving bowel functions and the microbiome). Many of these reputations are being supported by new research on the role of bitter receptors in the mouth and elsewhere round the body. Bitters were also seen as ‘cooling’ reducing the intensity of some fevers and inflammatory diseases.
Bland
Blandness refers to a mild, plain, non-stimulating taste and an energetic action that neither irritates nor strongly activates physiological processes. In traditional Chinese medicine, bland substances gently drain dampness and promote urination, relieving excess fluid whilst also preserving qi and yin. Western traditional medicine similarly associates healing with bland substances that avoid extremes of heat or cold and promote restoration of balance. Blandness signifies regulation by supporting elimination and normal tissue function without forceful stimulation, helping to create a gentle and balanced state of homeostasis.
Cooling
Traditional ‘cold’ or cooling’ remedies often contain bitter phytonutrients such a iridoids (gentian), sesiquterpenes (chamomile), anthraquinones (rhubarb root), mucilages (marshmallow), some alkaloids and flavonoids. They tend to influence the digestive system, liver and kidneys. Cooling herbs do just that; they diffuse, drain and clear heat from areas of inflammation, redness and irritation. Sweet, bitter and astringent herbs tend to be cooling.
Hot

Traditional ‘hot’ or ‘heating’ remedies, often containing spice ingredients like capsaicin, the gingerols (ginger), piperine (black or long pepper), curcumin (turmeric) or the sulfurous isothiocyanates from mustard, horseradish or wasabi, generate warmth when taken.

In modern times this might translate as thermogenic and circulatory stimulant effects. There is evidence of improved tissue blood flow with such remedies: this would lead to a reduction in build-up of metabolites and tissue damage.

Heating remedies were used to counter the impact of cold, reducing any symptoms made worse in the cold.

Mucilaginous
Mucilages are complex carbohydrate based plant constituents with a slimy or ‘unctuous’ feel especially when chewed or macerated in water. Their effect is due simply to their physical coating exposed surfaces. From prehistory they were most often used as wound remedies for their soothing and healing effects on damaged tissues. Nowadays they are used more for these effects on the digestive lining, from the throat to the stomach, where they can relieve irritation and inflammation such as pharyngitis and gastritis. Some of the prominent mucilaginous remedies like slippery elm, aloe vera and the seaweeds can be used as physical buffers to reduce the harm and pain caused by reflux of excess stomach acid. Mucilages are also widely used to reduce dry coughing. Here the effect seems to be by reflex through embryonic nerve connections: reduced signals from the upper digestive wall appear to translate as reduced activity of airway muscles and increased activity of airway mucus cells. Some seed mucilages, such as in psyllium seed, flaxseed (linseed) or guar bean survive digestion to provide bulking laxative effects in the bowel. These can also reduce rate of absorption of sugar and cholesterol.
Neutral
Neutral herbs are characterised as by balanced temperature and energetics — neither warming nor cooling, nor strongly dispersing nor consolidating, and are, therefore, used across a wide spectrum of constitutional and pathological states. In Chinese medicine, this level, calm quality supports the centre, and gently strengthens digestion, regulates fluids, and resolves damp without provoking too much heat or cold. In Western medicine, neutral herbs are regarded as equal in relation to hot/cold or damp/dry and capable of maintaining a state of equilibrium. Neutral herbs can be seen as moderating reactivity, and supporting homeostasis rather than forcing change.
Pungent
The pungent flavour refers to the powerful taste of hot spices including mustard (Brassica spp.), ginger (Zingiber officinale), horseradish (Amoracia rusticana), chilli (Capsicum spp.), and garlic (Allium sativum). These herbs act to enliven and invigorate the senses, and they often also have heating qualities. Unlike other tastes, the effect is not linked to a specific receptor on the tongue and instead acts through direct irritation of tissues and nerve endings. Energetically, pungent herbs are known to disperse energy (qi) throughout the body. Pharmacologically, pungent herbs dry excess moisture and mucus, as well as stimulate digestion and metabolism.
Resinous
Resins are most familiar as tacky discharges from pine trees (and as the substance in amber, and rosin for violin bows). They were most valued however as the basis of ancient commodities like frankincense and myrrh (two of the three gifts of the Three Wise Men to the baby Jesus) and getting access to their source was one benefit to Solomon for marrying the Queen of Sheba (now Ethiopia). Resins were the original antiseptic remedies, ground and applied as powders or pastes to wounds or inflamed tissues, and were also used for mummification. With alcohol distillation it was found that they could be dissolved in 90% alcohol and in this form they remain a most powerful mouthwash and gargle, for infected sore throats and gum disease. They never attracted much early research interest because they permanently coat expensive glassware! For use in the mouth, gums and throat hey are best combined with concentrated licorice extracts to keep the resins in suspension and add extra soothing properties. It appears that they work both as local antiseptics and by stimulating white blood cell activity under the mucosal surface. They feel extremely effective!
Salty
The salty flavour is immediately distinctive. A grain dropped onto the tongue is instantly moistening and a sprinkle on food enkindles digestion. This easily recognisable flavour has its receptors right at the front of the tongue. The salty flavor creates moisture and heat, a sinking and heavy effect which is very grounding for the nervous system and encourages stability. People who are solid and reliable become known as ‘the salt of the earth'.
Sharp
The sharp taste of some fruits, and almost all unripe fruits, as well as vinegar and fermented foods, is produced by weak acids (the taste is generated by H+ ions from acids stimulating the sour taste buds). Sour taste buds are hard-wired to generate immediate reflex responses elsewhere in the body. Anyone who likes the refreshing taste of lemon or other citrus in the morning will know that one reflex effect is increased saliva production. Other effects are subjective rather than confirmed by research but there is a consistent view that they include increased digestive activity and contraction of the gallbladder.
Sour
The sour taste occurs because of the stimulation of hydrogen ions which trigger the sour taste receptors on the tongue. The more acidic a substance, the more hydrogen ions will be released. The sour taste comes from acidic substances including citrus, fermented foods, tannins, and vinegars. Sour foods and herbs absorb excess moisture, whilst also increasing the production of saliva. Energetically, sour substances tonify the lungs, playing a role in disease prevention. Excessive use, however, can result in malabsorption of nutrients. Examples of sour herbs include, rosehips (Rosa canina), raspberry (Rubus idaeus), rhubarb (Rheum palmatum), schisandra (Schisandra chinensis), hawthorn (Crataegus monogyna) and ginkgo (Ginkgo biloba).
Sweet
In the days when most people never tasted sugar, ‘sweetness’ was associated with the taste of basic foods: that of cooked vegetables, cereals and meat. In other words sweet was the quality of nourishment, and ‘tonic’ remedies. Describing a remedy as sweet generally led to that remedy being used in convalescence or recovery from illness. Interestingly, the plant constituents most often found in classic tonics like licorice, ginseng are plant steroids including saponins, which also have a sweet taste.
Umami
The umami taste was originally discovered in 1985 in Japan and is directly translated from the Japanese as a ‘pleasant savoury taste’. It is referred to as the ‘fifth taste’ and is a salty, rich, and meaty flavour. The umami flavour is produced by amino acids (glutamic acid and aspartic acid) found in many food and plant sources including tomatoes, mushrooms, seaweeds and soy-based foods. Umami foods can improve nutritional absorption and digestion as there are also umami receptors in the gut as well as the mouth. Examples of umami herbs include green tea (Camellia sinensis), reishi (Ganoderma lucidum), nettle (Urtica dioica), cordyceps (Ophiocordyceps sinensis), shitake (Lentinula edodes) and bladderwrack (Fucus vesiculosus).
