  • How does it feel?

    Rosehips have a dynamic taste profile with an initial sweet zing followed by a sour or sharp taste sensation. From a flavour perspective, they could be seen as a native schisandra (Schidandra chinensis) — a popular Chinese medicine also known as five flavour berry due to its dynamic taste profile. Rosehip is sweet, sour, salty, aromatic and astringent. As a tea, syrup or tincture — its taste is enjoyed by most, making it a fantastic remedy for all the family.

  • What can I use it for?

    Rosehip (Rosa canina)
    Rosehip (Rosa canina)

    Rosehips are a wonderful and simple foraged food and medicine that can be harvested in autumn and made into a wide range of medicines. Although it is important to note that one must firstly remove the hairy seeds as they are an irritant to the digestive system. The flesh is high in antioxidant compounds, vitamins and minerals making it a truly valuable nutritive tonic. It is thought to be one of most potent sources of vitamin C found in any fruit or vegetable, hence rosehips are often used in vitamin C supplements (1).

    Rosehips’ medicinal properties are much attributed to their astringent and antioxidant actions. The tea is also beneficial as a demulcent for treating a sore throat. Rosehip can be an excellent support to the immune system for colds and acute viral infections. They can be used as a preventative throughout the early stages of a virus and to treat the symptoms throughout. They have been shown to exhibit antiviral properties by inhibiting viral replication (2). Rosehips are also an excellent tonic to help in the convalescence stages of such illnesses.

    Their anti-inflammatory effects are useful as part of a supportive approach for rheumatic conditions such as rheumatoid arthritis and osteoarthritis (3). However, when treating more chronic, life-limiting conditions it is recommended to consult with a professional herbalist. In traditional Chinese medicine (TCM), rosehips are used to promote the movement of qi and blood in the lower abdomen and, therefore, are often used to alleviate painful and heavy menstruation (4).

    Rosehips are renowned not only for internal use, but also externally as a popular cosmetic to support healthy, glowing skin. Its rich vitamin C and antioxidant content prevent oxidative stress on the skin cells, reduce scarring and support skin elasticity (5). It is often referred to as an anti-ageing agent, due to the moisturising effects of the fatty acids and presence of retinoids which promote skin regeneration (5).

  • Into the heart of rosehip

    Rosehip (Rosa canina)
    Rosehip (Rosa canina)

    Energetically, rosehips are sweet and cooling. They also have an interestingly contrasting action upon the tissues. They have both toning, astringent qualities but are also soothing and demulcent.

    The actions of astringent plants such as those found in the rose family (i.e. lady’s mantle (Alchemilla vulgaris), hawthorn (Crataegus monogyna) and rose flower (Rosa damascena) are all valuable for this strengthening effect on the mucous membranes. They have the ability to tone and moderate tension, improving the boundaries between the inner and outer regions. It is the additional mucilaginous quality of rosehips that also soothes, coats and protects the tissues (6).

    Rosehips’ effects on the tissues are fairly neutral due to these contrasting actions. This means that it works as an amphoteric to bring balance. This may be applied where there is a loss of tone. Contrastingly, it may also be applied where there is an excess in tension, which is sometimes indicated by a spasmodic or excited tissue state or by a dry, irritated and inflamed state in the mucous membranes. A herbalist will use rosehip to balance and restore integrity in the tissues (6).

    These actions are also understood to work on emotional boundaries. Rose has long been associated with the emotional heart and feelings of love. As a herb that works on the emotional heart, rosehip is also understood to bring healing in grief, loss and depressive states. Much like the flowering parts of rose, which are also used in herbal medicine. 

    The holistic understanding of the interconnectedness between the physical and emotional systems indicates that often where there is emotional tension, there is also physical tension. Rosehip (and rose alike) would, therefore, be a supportive choice to alleviate both.

    In Ayurvedic medicine, there is a different model and understanding of what each organ does and how they connect. Ayurveda has its own unique philosophy and understanding of bodily systems and herbal qualities that have been built up over thousands of years of observation.

    According to the Ayurvedic understanding of herbal energetics, rosehip is sour and astringent. The ayurvedic tradition describes rosehip as warming. . In terms of the doshas, rosehip is used to reduce excess vata and raise the qualities of kapha and pitta (7).

  • Traditional uses

    Rosehip (Rosa canina)
    Rosehip (Rosa canina)

    Traditional uses of rosehip in history were based on its astringent properties. It was believed to strengthen the stomach and alleviate diarrhoea, dysentery, thirst, cough, and spitting of blood (8).

    Nicholas Culpeper, a 17th century herbalist and physician stated that ripe hips made into a conserve (a preparation typically made with sugar or honey) would “gently bind the belly, and stay the flow of humours, or body fluids from the head upon the stomach, drying up the moisture thereof, and promoting digestion”. He also describes that rosehips were used in a dried, powdered form to break up stones, promote urination, and ease colic (8).

    Mrs Greive, a herbalist of the early 1900s writes that rosehips “were long official in the British Pharmacopoeia for refrigerant and astringent properties” (9).

    The known relationship between human use of rosehips dates back far in history. Remains of its fruits are dated to prehistoric settlements and prove its value to early societies. The writings of ancient Greek physician Hippocrates (460–377 BCE) and Roman naturalist Pliny the Elder (23–79 CE) may be the earliest reference to this plant as “the dog rose”. It is thought that it was so named for the belief that it cured the bite of rabid dogs.

    Pliny the Elder in the 1st century told the story of a woman who received a message in a dream. It describes that in the woman’s dream, she was asked to send her son, a soldier, a decoction of wild (dog) rose root. The decoction, known to the Greeks as Cynorrhodon, cured a mad dog’s bite (10).

  • Traditional 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.

  • Traditional energetic actions

    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 practitioners say

    Cardiovascular systemCardiovascular system

    Rosehips’ antioxidant properties support and protect the heart and cardiovascular system. They enhance the integrity of the entire vascular system reducing capillary fragility and permeability. Rosehips are used for the long-term treatment of varicose veins and degenerative vascular diseases, such as atherosclerosis and hypertension (11. Rosehips have been shown to reduce LDL cholesterol, lower blood pressure and reduce the risk of cardiovascular disease (11). 

    Immune system

    Due to the high levels of antioxidants, vitamin C and nutritive compounds in rosehip, it is used by herbalists to support and strengthen the immune system. It is also an immunomodulator, which is one of the ways by which it helps to lower the inflammatory effects of autoimmune conditions, such as rheumatoid arthritis. Rosehips have also been shown to stimulate the production of white blood cells, help to improve immune resistance and protect against infections (12). 

    Musculoskeletal system

    Rosehip has a number of indications for inflammatory conditions in the musculoskeletal system, such as rheumatoid arthritis and osteoarthritis. Herbalists use rosehip to reduce inflammation and pain via a modulating effect on the immune system. Rosehip inhibits proinflammatory cytokines and NF-κB signaling and reduces C-reactive protein (13). Rosehip powder has also been effective in reducing pain and inflammation amongst patients with osteoarthritis and rheumatoid arthritis (13,14). 

    Urinary system

    Rosehip has a diuretic action, which means that it can be used for conditions of the kidneys and lower urinary tract. It is highly antioxidant and also supports blood purification through the kidneys. Rosehip is an excellent medicine to support healing in the urinary tract during and after an acute urinary tract infection, providing the infection has been appropriately managed (3).

    Digestive system

    Rosehip infusion coats and soothes the mucous membranes, due to its mucilaginous properties. The mucilage coats the digestive tract, calming and protecting the digestive tissues after acute stomach illness, antibiotic use, dysentery, or giardia. The mucilaginous quality soothes the digestive tract and helps to alleviate constipation (15).

    Skin health

    A topical preparation of rosehip is used for a variety of skin complaints. Research suggests that it can aid in the healing of surgical wounds and ulcers. Rosehips have been shown to promote collagen synthesis and support skin repair and regeneration. The retinoids also facilitate skin cell turnover and reduce inflammation. This contributes to its use in skin care products to support ageing skin (5). 

  • Research

    Rosehip (Rosa canina)
    Rosehip (Rosa canina)

    The effects of a standardised herbal remedy made from a subtype of Rosa canina in patients with osteoarthritis: A double-blind, randomised, placebo-controlled clinical trial

    This trial explored the effect an extract made from rosehip powder had on joint mobility, daily life, quality of life and pain in osteoarthritis patients. One hundred participants were included, with half receiving five doses of 0.5 g of rosehip powder extract twice daily for four months and the other half receiving placebo. The results showed significant improvement in joint mobility and a reduction in pain in the rosehip group compared to placebo (16). 

    Effects of daily Intake of rosehip extract on low-density lipoprotein cholesterol and blood glucose levels: A systematic review

    This systematic review analysed four randomised clinical trials that studied the impact of rosehips on lipid profiles and blood glucose levels. The dosages varied between 40 g powder to 100 mg to 750 mg in tablets taken once or twice daily for between 6–12 weeks. Results showed significant reductions in LDL cholesterol, fasting blood glucose and HbA1c. Secondary measures included reductions in body weight, systolic blood pressure, abdominal fat and cardiovascular risk scores. Rosehip was well tolerated with limited adverse effects (11).

    Bioactive ingredients of rose hips (Rosa canina L) with special reference to antioxidative and anti-inflammatory properties

    A review was carried out on a number of in vitro studies that investigated the effects of different compounds extracted from rosehips. A promising body of evidence is compiled which shows the actions of many compounds found in rosehips such as flavonoids, carotenes, polyphenols and essential fatty acids shows a clear evidence base for being anti-inflammatory and exhibiting antioxidant mechanisms in vitro. As these in vitro studies focus on extractions presented to cells in a test tube they lack true insight into how biologically complex whole plant extracts work in the human body. It is clear that further clinical trials with larger sample sizes are needed (12).

    Rose hip herbal remedy in patients with rheumatoid arthritis — a randomised controlled trial

    A double-blind placebo-controlled trial was carried out to investigate the effectiveness of rosehip on 89 patients with rheumatoid arthritis. Subjects were randomised to receive treatment with capsulated rose-hip powder at 5 g daily or with a placebo over a period of six months. The results show that the rosehip group made significant improvements in various pain measurements, as well as parameters that indicate quality of life. The placebo group, however, worsened. This indicates that rosehip is effective in treating patients with rheumatoid arthritis (18).

    Does the hip powder of Rosa canina (rosehip) reduce pain in osteoarthritis patients? A meta-analysis of randomized controlled trials

    A meta-analysis of randomised controlled trials was carried out on rosehip powder for the treatment of osteoarthritis. Overall, three studies were evaluated with a cumulative study group of 306 patients. The studies showed a reduction in pain scores in the rosehip powder group when compared with the placebo group (19).

    The effectiveness of a standardised rose hip powder, containing seeds and shells of Rosa canina, on cell longevity, skin wrinkles, moisture, and elasticity

    During an eight week double blind study the effects of rosehip powder on skin ageing were investigated. A total of 34 healthy subjects, aged 35–65 years who received the rosehip displayed significant improvements in crow’s feet, wrinkles, skin moisture, and elasticity. The study concludes that rosehip taken internally has several anti-ageing properties (14).

    Rosehip oil promotes excisional wound healing by accelerating the phenotypic transition of macrophages

    Results showed that rosehip oil significantly promoted wound healing and effectively improved scars. This efficacy might have happened because of accelerating macrophage phenotypes transition to the wound. Macrophages are types of white blood cells that facilitate wound healing, and there are different types that release different chemical signals that facilitate the healing process. Rosehip was shown to increase this mechanism of action. The oil also helped with improving scars as it inhibited the process of epithelial-mesenchymal transition which is a tissue forming process which causes scars (19).

    Effects of rose hip intake on risk markers of type 2 diabetes and cardiovascular disease: a randomised, double-blind, cross-over investigation in obese persons

    A randomised, double-blind, cross-over investigation was carried out to evaluate the effects of rosehip powder drink (40 g powder) on risk markers of type 2 diabetes and cardiovascular disease in obese subjects. A total of 31 obese individuals with normal or impaired glucose tolerance were enrolled. The study results showed that six weeks of daily consumption of the rosehip drink resulted in a significant reduction of systolic blood pressure, total plasma cholesterol, low-density lipoprotein (LDL) cholesterol and LDL/HDL ratios. The study concludes that rosehip powder can significantly reduce the risk of cardiovascular disease in obese people through the lowering of systolic blood pressure and plasma cholesterol levels (20).

  • Habitat

    Rosehips are native to Europe and are the most common Rosa species with the widest distribution in central Europe. The shrub is most often found in hedgerows, woodland edges and scrubland (25).

  • Sustainability

    The commercial supply of rosehips is obtained primarily from wild-harvested sources in Eastern Europe. According to the IUCN Red List of Threatened Plants Status wild populations of dog rose remain abundant and it is classified as ‘least concern’ (26).

    Sustainable wild-collection of dog rose fruit requires harvesting in a way that does not destroy twigs and branches. Sustainable herbs program suggests that a minimum of 20% of any individual plant’s fruits should be left on the tree to facilitate regeneration (8). Controlled cultivation of rosehips along with improved organic agriculture rules in wild harvesting of this species means that for a large majority — the global demand for rosehips can still be met through sustainable production methods (27).

    Habitat loss and over-harvesting from the wild are two of the biggest threats faced by medicinal plant species. There are an increasing number of well-known herbal medicines at risk of extinction. We must, therefore, ensure that we source our medicines with sustainability in mind.

    The herb supplement industry is growing at a rapid rate and until recent years a vast majority of medicinal plant produce in global trade was of unknown origin. There are some very real and urgent issues surrounding sustainability in the herb industry. These include environmental factors that affect the medicinal viability of herbs, the safety of the habitats that they are taken from, as well as the welfare of workers in the trade.

    The botanical supply chain efforts for improved visibility (transparency and traceability) into verifiably sustainable production sites around the world is now certificated through the emergence of credible international voluntary sustainability standards (VSS).

  • Quality control

    Rose (Rosa centifolia)
    Rose (Rosa centifolia)

    Older texts suggest that it is best to harvest rosehips after the first frost. The frost breaks down the cell walls of the fruit, thereby giving you more liquid once the fruit is cooked. However in many places where rosehip grows the first frost is long after the fruiting season. The fruits may well rot or be eaten by birds and insects before which time. As a solution, one can simply freeze rosehips for 24 hours to optimise the flavour before using (29).

    Herbal medicines are often very safe to take; however, their safety and efficacy can be jeopardised by quality issues. So, it is important to buy herbal medicines from a reputable supplier, from sources known to test their herbs to ensure there is no contamination, adulteration or substitution with incorrect plant matter, as well as ensuring that recognised marker compounds are at appropriate levels in the herbs.

    Some important quality assurances to look for are certified organic labelling, the correct scientific/botanical name, and the availability of information from the supplier about ingredient origins. A supplier should be able to tell you where the herbs have come from, what contaminants are not in the herb, and what the primary compounds are.

  • How to grow

    Dog rose is a hardy shrub which is easy to grow. It will thrive in full to partial sun placed usually in the middle or back of a garden border or edge.It is advised to source a small bare-root plant through a local garden centre, although a more advanced gardener may grow a rose from seed or more commonly from hardwood cuttings.

    Dog rose is best planted out in autumn but failing that, it can be planted in early spring.

    Place your bare rooted rose directly into a moist but well-drained soil either straight in situ or in a large ceramic pot.

    This species requires little feeding but will benefit from a feed in spring using an organic fertiliser. This will encourage good growth. Choose a fertiliser which is high in potash, such as tomato fertiliser.

    Roses need watering occasionally during the warmer months, particularly in hotter climes.

    To maintain its shape, prune back older stems to around 30 cm above ground level, from late autumn to early spring (29).

  • Recipe

    Rosehip syrup

    Rosehip syrup is a popular recipe among herbalists and foragers. It is sweet, zingy, incredibly healthy and easy to make. This recipe uses honey instead of refined sugar. However, sugar can be used instead. To make a syrup using fruiting plant medicines, one must first make a decoction or infusion. Follow the steps below.

    Ingredients

    • Rosehips
    • Honey or sugar
    • Water

    How to make rosehip syrup

    • Gather the rosehips or source dried rosehips from a local health food shop or herbalist. Freshly gathered whole rosehips will need deseeding. This is easy enough to do by cutting rosehips in half and gently scooping out the hairy seeds with a spoon. Ensure to remove them all and the tiny hairs as they can be an irritant to the digestive tract.
    • Place your processed rosehips in a sieve and give them a rinse after removing the seeds, this will help wash away any tiny hairs that are stuck to the fruit.
    • Place rosehips into a pot adding water at a ratio of around one part rose hips to two parts water (1:2). Bring it to a boil, then reduce the heat and simmer for 15–20 minutes, or until the water has reduced by about half.
    • Remove the decoction from the heat and leave to cool for 10 or so minutes allowing for that final extraction before straining out the plant material into a sterile bowl. This may be done using cheesecloth (a minimum of three layers — to remove any remaining hairs) on top of a fine mesh sieve.
    • Take a good look, and if there are still tiny hairs floating around it’s a good idea to strain it once again, maybe with even more layers of cheesecloth.
    • Measure the quantity of decoction and then return to a clean pan on very low heat.
    • Measure out the honey, or sugar. Using no less than three parts honey to one part decoction (1:3) to effectively preserve your syrup. Stir through the honey until it has fully dissolved.
    • If you have a large quantity of decoction, you may simmer it down for a further 20- 30 minutes before adding honey or choose to store some in the freezer. 
    • Bottle up the syrup into sterile glass bottles and store in the fridge. It should last for up to six months.

    Adults can take 1–2 tablespoons of rosehip syrup 2–3 times a day as a daily nutritive tonic to support health, though if one is diabetic then high sugar levels should be avoided. It can also be taken at the onset of a cold or flu. Children aged over one year may take 1 tsp a day and those aged three and up, can take 2–3 tsp a day. Rosehip syrup can also be used in smoothies, as a drizzle over deserts or in cocktails and smoothies.

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 (eg 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.
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, horseradich 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. .
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).
