Vrikshamla (Kokum) in Ayurveda: Properties & Everyday Use

What it is

Vrikshamla is kokum: the dried rind of the fruit of Garcinia indica Choisy, a member of the evergreen tropical Garcinia genus (gastritis RCT background). The rind is used both as a souring agent in coastal Indian cooking and in traditional medicine. Its characteristic studied compound is garcinol, the marker used to standardize the extract in the human liver-function trial below (Mashiki et al., 2025).

Important distinction: kokum is a different species from Garcinia cambogia (also sold as G. gummi-gutta), the source of "garcinia" weight-loss supplements. The human trials of cambogia extracts for weight loss tested a different plant: their results do not transfer to kokum, and no human trial has tested kokum for weight loss.

Classical properties

• Taste (rasa): sour (Amla)
• Qualities (guna): light (Laghu)
• Potency (virya): warming (Ushna)
• After digestion (vipaka): pungent (Katu)
• Doshas: traditionally said to settle Kapha; may increase Pitta

Traditional use

In Indian traditional medicine, kokum fruit rinds are described for the digestive tract, including gastric ulcers, bowel complaints and other inflammatory conditions (gastritis RCT background). These are traditional descriptions, not clinical proof: the two human studies are assessed separately below.

What research has looked at

Chronic gastritis

In a randomized controlled trial, 60 patients with chronic gastritis were randomized to kokum rind extract with honey (n=30) or warm water (n=30) for 3 weeks (Swathi et al., Nutr Food Health Dis). The kokum group showed significant decreases in gastrointestinal symptoms (p<0.0001), significant quality-of-life improvements on the Izumo scale (p<0.0001), and improved gastric myoelectrical activity on electrogastrogram (p<0.0001); the warm-water control group showed no significant changes. Caveats: the control was warm water rather than a matched placebo (no blinding of a honey-containing preparation), the trial lasted only 3 weeks, and the honey co-intervention means the effect cannot be attributed to kokum alone.

Liver enzymes (garcinol)

A 2025 randomized, double-blind, placebo-controlled, parallel-group trial in 80 healthy adults (aged 20–64) gave the active group a food containing G. indica extract standardized for garcinol, for 12 weeks (Mashiki et al., Food and Nutrition Sciences). ALT and AST were significantly lower in the active group than the placebo group after 12 weeks (p<0.05), with no serious adverse events. Caveats: participants' enzymes were already within the normal range at baseline (the effect was a small shift within normal, not treatment of liver disease), the authors were affiliated with a food company (Toyo Shinyaku Co.), and the publishing journal (SCIRP's Food and Nutrition Sciences) is not a top-tier venue: treat this as preliminary.

What the evidence does not support (yet)

What no human trial of kokum supports: weight loss, ulcer healing, or treating liver disease. The gastritis trial measured symptoms over 3 weeks, not ulcer healing; the garcinol trial enrolled healthy adults, not liver patients.

Safety notes

Neither trial reported serious adverse events attributable to kokum (Swathi et al.; Mashiki et al., 2025), and the gastritis-trial authors described kokum rind with honey as "a safe home remedy." That said, supplement-level safety data are limited to short trials (3 and 12 weeks). There are no human safety data for pregnancy or breastfeeding. Do not confuse kokum products with Garcinia cambogia weight-loss supplements: they are different species, and the cambogia weight-loss trial data do not apply to kokum.

FAQs

What is vrikshamla (kokum)?

Vrikshamla is the Ayurvedic name for kokum: the dried fruit rind of Garcinia indica, an evergreen tropical tree. It is used as a souring agent in coastal Indian cooking and traditionally for gastric and bowel complaints (gastritis RCT background).

Is kokum the same as Garcinia cambogia?

No. They are different species. Garcinia cambogia is the source of "garcinia" weight-loss supplements; kokum is Garcinia indica. Human weight-loss trials tested cambogia extracts, not kokum: and no human trial has tested kokum for weight loss.

Does kokum help gastritis?

One small 3-week randomized trial (n=60) found kokum rind extract with honey reduced chronic-gastritis symptoms and improved quality-of-life scores versus warm water (Swathi et al.). It was unblinded, short, and honey was a co-intervention: encouraging but preliminary.

Does kokum help the liver?

A 12-week trial of a garcinol-standardized G. indica extract in 80 healthy adults found modestly lower ALT and AST versus placebo: but enzymes were already normal at baseline, so this is not evidence of treating liver disease (Mashiki et al., 2025).

Is kokum safe?

In the two short human trials (3 and 12 weeks), no serious adverse events were reported, and kokum has a long culinary history as a food. Longer-term supplement safety data do not exist; there are no data for pregnancy or breastfeeding.
