Kapittha is the fruit of Limonia acidissima, a hard-shelled tree fruit of India and Sri Lanka known in English as wood apple. In Ayurveda it is a single drug, used mostly for digestive complaints. The sour-sweet pulp is the part used; leaves and bark appear in folk practice.
People take it most often for loose stools, weak appetite, nausea and thirst. It is as much a food as a medicine, eaten across South Asia as chutney, jam and a cold sherbet drink.
The short verdict on evidence: the traditional record is long and clear, but human trial evidence is essentially absent. Long use in a tradition is not proof that something works, and that gap applies to everything on this page.
No one has shown how Kapittha works in the human body. The simplest explanation is mechanical: the pulp is rich in tannins (astringent plant compounds that tighten tissue) and soluble fibre, which can firm loose stools and slow the gut.
Ayurvedic texts describe the fruit as sour and astringent in taste. They say it steadies the digestive fire and calms vata and kapha. That is a traditional model of the body, not a measured mechanism.
Laboratory work reports antioxidant activity, and rodent studies report lower blood sugar after wood apple extracts. Those results come from test tubes and animals. They do not tell you what happens in a person.
You will most often meet Kapittha as fresh fruit pulp scooped from the shell, as a dried pulp powder, or as a sweet-sour sherbet drink.
It is also sold as chutney, jam and candy. In Ayurvedic pharmacies it appears inside compound powders such as Kapitthashtaka churna. Leaf juice and bark decoctions (water boiled with the plant part) are used in some village practice but are far less common.
Kapittha is named in the classical Ayurvedic texts, including the Charaka Samhita and Sushruta Samhita, and again in the later Bhavaprakasha Nighantu. That puts its recorded medicinal use in India at well over 1,500 years.
It has stayed in everyday use as both food and home remedy in India, Sri Lanka, Bangladesh and parts of Southeast Asia.
See a doctor if diarrhoea lasts more than three days, if there is blood in your stool, or if you cannot keep fluids down.
Get urgent help for signs of dehydration in a child or older person: sunken eyes, no wet nappies or no urine for many hours, drowsiness or confusion.
Get emergency help for swelling of the face, lips or throat, or for trouble breathing after taking it. If you have diabetes and feel shaky, sweaty or confused, check your blood sugar straight away and treat a low reading.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Kapittha is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
