Kokum

Kokum takes its English name from the Konkani and Marathi word for the fruit, and is known by the same name, or close variants such as Kokam, across most of India. It grows on an evergreen tree native to the coastal Western Ghats of India, particularly Goa, Karnataka, Maharashtra and Kerala, and has been used for centuries in South Asian cooking and traditional medicine. The dried rind, juice, seeds and seed fat, kokum butter, are all put to use, most often as a natural souring agent in place of tamarind or lemon.

In classical Ayurvedic texts, including the Charaka Samhita and Bhava Prakasha, kokum's fruit is described as having an Amla (sour) Rasa (taste), Laghu (light) and Ruksha (dry) Guna (qualities), an Ushna (heating) Virya (potency), and an Amla (sour) Vipaka (post-digestive effect). It is traditionally described as helping to balance Kapha and Vata.

Kokum is known by several genuine regional names across India:

• Botanical name: Garcinia indica
• Hindi: Kokum, Kokam, Bhirand, Ratambi
• Marathi: Amsul, Bhirand, Kokambi, Ratamba
• Konkani: Bhirind
• Kannada: Dhupadamara, Murgala, Murgina, Punarpuli, Tittidika
• Malayalam: Kaattampi, Kokkam
• Tamil: Murgal, Murgal-mara
• Gujarati: Kokam, Kokambi, Ratamba
• Bengali: Mahada
• Odia: Tintali
• English: Kokum, Goa butter tree, Indian tallow tree, wild mangosteen

Kokum's properties come mainly from the following compounds identified in its fruit and rind (Lim et al., 2021):

• Hydroxycitric acid (HCA), the main organic acid in the fruit rind, which contributes to much of its sour taste
• Garcinol, a polyphenolic compound found in the fruit and seeds
• Anthocyanins, the pigments responsible for the fruit's deep purple-red colour
• Malic acid and citric acid, contributing further to the fruit's tartness

Per 100g, dried kokum rind provides approximately the following (Chate, 2019):

Based on its traditional use and its studied compounds, Kokum's rind and fruit are traditionally used or have been studied for the following actions on the body:

• Digestive, traditionally used to stimulate digestion and ease mild indigestion
• Astringent, traditionally used to help tone and settle the gut
• Antioxidant, its anthocyanin and polyphenol content has antioxidant activity and may help neutralise free radicals
• Antimicrobial, laboratory studies suggest activity against certain micro-organisms
• Mild anti-inflammatory, studied mainly in relation to its garcinol content

These properties are drawn mainly from traditional Ayurvedic use and from laboratory and animal research; robust human clinical trials for most of these effects are limited (Lim et al., 2021). Kokum is best regarded as a traditional culinary and digestive ingredient rather than a treatment for any diagnosed medical condition.

Kokum is traditionally used to support digestion and general wellbeing, while its compounds have also been studied for antioxidant and other potential effects. Kokum and kokum butter are used in food and traditional skin care practices, respectively. However, evidence for specific health outcomes such as weight loss or treatment of chronic diseases remains limited.

Traditional Support for Digestion

Kokum's sour rind is traditionally used in Ayurveda to help stimulate digestion and ease occasional acidity, indigestion or bloating. It is a traditional digestive aid rather than a cure, and persistent digestive symptoms need medical assessment rather than home treatment alone.

Antioxidant and Anti-Inflammatory Compounds

Kokum contains garcinol, a polyphenol studied for its antioxidant and anti-inflammatory activity in laboratory research (Lim et al., 2021). Including antioxidant-rich foods such as kokum as part of a varied diet is traditionally believed to support general wellbeing.

Traditional Use in Weight Management

The hydroxycitric acid (HCA) in kokum's rind is associated with effects on appetite and fat metabolism in some studies. Human evidence for a meaningful weight-loss effect from Garcinia species is limited and mixed, so kokum should not be relied on as a weight-loss treatment.

Culinary Use as a Refreshing Drink

Kokum sherbet is a popular traditional drink across Western India, especially in summer, valued for its refreshing, tangy taste and its traditional use to support digestion after a meal.

Traditional Use for General Wellbeing

Kokum has a long history of traditional use in Ayurveda and South Asian home cooking, valued for its taste, its digestive use and its place in traditional diets. It is not a treatment for diabetes, high or low blood pressure, or heart disease, and should not be used in place of prescribed medicine for any of these conditions.

Kokum Butter for Skin

Kokum butter, extracted from the seeds, is rich in fatty acids and is traditionally used as a moisturiser for dry or cracked skin. It is applied externally only and should not be assumed to have an established internal medicinal use in this form.

Acts as a Natural Coolant

Kokum’s cooling nature is traditionally believed to help refresh the body during hot weather. Traditional Kokum sherbet is consumed in hot climates for its refreshing, tangy taste, but there is limited evidence that it can prevent heatstroke, restore hydration or balance electrolytes. It should not be relied upon to prevent or treat heat-related illness.

Beyond its place in Ayurveda, Kokum is used in a few everyday contexts:

Kokum Sherbet as a Traditional Drink

Kokum sherbet, also called kokum sharbat, is a popular traditional drink across Western India, made by diluting kokum syrup or juice in water, often with a pinch of cumin and salt, and traditionally used to support digestion after a meal.

Souring Agent in Curries and Soups

Dried kokum rind is commonly added to curries, soups and dal in place of tamarind or lemon, giving dishes a distinct tangy flavour, particularly in Goan, Konkani and coastal Maharashtrian cooking.

Kokum Butter in Skincare

Kokum butter, extracted from the seeds, is used topically to moisturise and help soothe dry or cracked skin, and is a common ingredient in traditional and commercial skincare balms.

• Avoid frequent, concentrated use, as Kokum's sour, acidic nature can trigger acidity or heartburn in some people if taken in large amounts.
• People with diabetes, or those on blood-sugar-lowering medicine, should use caution and monitor their blood glucose, since Kokum may lower blood glucose.
• People with high or low blood pressure, or those on blood pressure medicine, should speak to their doctor before regular medicinal use.
• People on blood-thinning medicine should speak to their doctor before regular medicinal use, since there is limited evidence that Kokum may affect blood clotting.
• Pregnant or breastfeeding women should consult a healthcare provider before using Kokum beyond normal food amounts, as robust safety evidence in pregnancy is limited.

Note: This information is not a substitute for professional medical advice. Speak to a doctor before using Kokum regularly for a health condition, especially if you have diabetes, high or low blood pressure, or are on regular medication.

Kokum is available in several forms, and how it is used differs by form:

Dried Rind

Dried kokum rind is soaked in warm water for a few minutes to soften, then added whole or chopped to curries, dals and soups towards the end of cooking for a tangy flavour.

Juice or Syrup

Kokum juice or syrup is diluted with water, usually with a pinch of cumin and salt to taste, to make a traditional drink.

Powder

Kokum powder can be stirred into water or mixed into marinades and spice blends as an alternative to the dried rind.

Kokum Butter

Kokum butter is applied directly to the skin as a moisturiser, either on its own or blended into a cream or balm, and is for external use only.

Capsules

Kokum capsules are taken by mouth with water, generally after a meal, following the product label or advice from a healthcare professional.

Herbs Traditionally Used With Kokum

Kokum is traditionally combined with a small number of other ingredients in cooking and traditional drinks:

Most people tolerate Kokum well as a food. The following effects may occur with excessive or concentrated use:

Digestive Upset

Taking too much Kokum, especially as concentrated juice, syrup or capsules, can cause gastrointestinal discomfort such as diarrhoea, an upset stomach or acidity.

Low Blood Sugar

Kokum may lower blood glucose levels. People with diabetes, especially those on blood-sugar-lowering medicine, should monitor their blood sugar closely and watch for symptoms of hypoglycaemia, such as shakiness, sweating or confusion.

Pitta Aggravation With Very Large Amounts

Classical Ayurvedic sources describe very large amounts of sour fruit as potentially aggravating Pitta, and a documented case of prolonged, excessive kokum intake has been linked to nosebleeds and a burning sensation in the throat. Normal culinary use is not generally associated with this risk.

Kokum may interact with the following types of medicine. This is not a complete list, and a doctor or pharmacist should always be told about regular kokum or kokum-supplement use:

Blood-Thinning Medicine (Anticoagulants and Antiplatelets)

Kokum may affect blood clotting, although evidence for a clinically significant interaction is limited. Anyone on blood-thinning medicine should check with their doctor before regular medicinal use of Kokum.

Diabetes Medicine

Kokum may lower blood glucose. Combining it with insulin or other blood-sugar-lowering medicine could potentially increase the risk of low blood sugar, so anyone on diabetes medicine should seek medical advice before regular use.

Blood Pressure Medicine

Kokum may affect blood pressure. Combining it with antihypertensive medicine could potentially lower blood pressure further, so anyone on blood pressure medicine should check with their doctor before regular use.

Storage of Kokum

• Dried kokum rind: store in an airtight container in a cool, dry place away from direct sunlight; it keeps well for several months to a year.
• Kokum syrup or juice: once opened, refrigerate and use within the timeframe given on the label.
• Kokum powder and capsules: store in an airtight container in a cool, dry place, away from moisture.
• Kokum butter: store in a cool place, since it may soften or melt in high heat; it can be kept in the refrigerator in warmer climates.

• Kokum (Garcinia indica) is a sour tropical fruit traditionally used in South Asian cooking and Ayurveda, mainly as a digestive souring agent.
• It is a source of dietary fibre, vitamin C, calcium and iron, and contains antioxidant compounds such as garcinol.
• It is traditionally used to support digestion and is used externally, as kokum butter, to moisturise dry skin.
• It is not a treatment for diabetes, high or low blood pressure or heart disease, and may interact with medicines for all three, so anyone on regular medication should check with their doctor before using it beyond normal food amounts.
