Gamboge Tree: Benefits, Uses & Dosage

Cut into the bark of the Gamboge Tree and it bleeds a bright yellow resin. That resin has served as both a pigment and one of the most forceful purgatives in the Ayurvedic materia medica, a medicine so strong that its classical dose is measured in single grains.

Known in Sanskrit as Tamala (Tamala) and in English as the Indian Gamboge Tree, its botanical name is Garcinia morella Desr. It is a large evergreen tree of the forests of the Western Ghats and Southern India, growing up to about 2000 feet, with thick, peeling bark. The bark yields roughly 40 percent resin, and the fruit is edible.

The Bhavaprakash Nighantu describes Tamala as bitter, hot and Kapha-cutting. This is a herb to understand and respect rather than one to experiment with: its value lies in skilled, supervised use.

The Bhavaprakash Nighantu, a medieval Ayurvedic materia medica, records Gamboge's actions in a short list. All of them trace back to the resin's bitter and astringent taste, light and dry qualities, and hot potency (Ushna Virya).

Powerful purgation

Gamboge resin is a drastic purgative. The classical text uses it in very small doses for constipation and dropsy (fluid swelling of the body). At larger doses it causes vomiting, which is why the dose is kept to mere grains.

Worms and parasites

Gamboge is classed as an anthelmintic (Krimighna, "worm-destroying"), and the resin is described as clearing worm infestations. This places it among classical remedies for parasites and worms.

Skin disease

The resin is described as clearing skin disorders (Kushtha), the broad classical category covering chronic skin disease. The text also lists it as a wound cleanser (Vranashodhana).

Balancing Kapha and Vata

Tamala is recorded as alleviating Kapha and Vata (Kaphavatahara). Its heat counters the cold of both, while its light, dry, cutting quality clears Kapha's heaviness and stagnation.

Gamboge is not a home herb. The resin is a drastic purgative, and the only classical dose in our sources is tiny. It is used in Ayurveda solely under the direction of a trained practitioner.

Our sources record no vehicle (Anupana) or seasonal guidance for Gamboge. The key fact is the dose: above the grain range the resin causes vomiting, so there is no safe margin for guessing.

Gamboge resin is a drastic purgative and should never be self-administered. Most Ayurvedic herbs have a comfortable margin between a useful and a harmful dose. Gamboge does not.

• Tiny therapeutic dose: the classical dose is just 1 to 2 grains of resin.
• Overdose signs: at larger doses the resin causes vomiting (emesis) on top of violent purgation.
• Heating and drying: its hot, dry, light nature makes it unsuitable for people who are already depleted, dehydrated or overheated.
• Practitioner supervision only: use it only if a qualified Ayurvedic practitioner prescribes and prepares it.
• Pregnancy, nursing, children and medication: our sources give no safety data. Given its strength, avoid it entirely in these situations.

The edible fruit is a separate matter from the medicinal resin. Our sources give no safety notes for it beyond calling it edible.

Gamboge has no everyday supplement equivalent. The comparisons that matter are between its own parts and forms.

Comparison	Gamboge Tree	Alternative	Verdict
Resin vs fruit	Resin: drastic purgative, 1 to 2 grains	Fruit: described as edible	The medicine is the resin; the fruit is food. Do not treat them as the same thing.
Small dose vs large dose	Small doses act as a purgative	Larger doses cause vomiting	The gap is narrow, which is why only a practitioner should dose it.
Medicine vs pigment	Used medicinally in Ayurveda	The same yellow resin is used as a pigment	Pigment-grade material is not a medicine and should never be ingested.

Pregnancy & Nursing

Do not use. Gamboge is a drastic purgative, our sources give no safety data for pregnancy or breastfeeding, and forceful purging is not appropriate at these times.

Children

Do not use. The classical dose is already measured in grains for adults, and no paediatric dose is recorded.

Elderly

Older adults tend toward dryness and depletion, which Gamboge's hot, dry, purgative action can worsen. Avoid it unless a practitioner specifically prescribes and supervises it.

Athletes

Gamboge has no strength-building or recovery action. Forceful purging would work against training, so it has no role here.
