Background

Tamarind is native to tropical Africa and grows wild throughout the Sudan. It was introduced to India thousands of years ago. In Jordan and other Middle Eastern countries, tamarind juice from the tamarind tree is made into a drink prepared by infusing dried tamarind pulp. It has also been used for the preservation of food products. Tamarind may be used as a paste and sauce and included in recipes. Tamarind is also used in India as part of Ayurvedic herbal medicine.
In animal studies, tamarind has been found to lower serum cholesterol and blood sugar levels. Due to a lack of available human clinical trials, there is insufficient evidence to recommend tamarind for the treatment of hypercholesterolemia (high cholesterol) or diabetes.
Based on human study, tamarind intake may delay the progression of fluorosis by enhancing excretion of fluoride. However, additional research is needed to confirm these results.

Tradition / Theory

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Dosing

Adults (18 years and older):
There is no proven safe or effective dose of tamarind. However, 10 grams daily for up to three weeks has been used to delay the progression of fluorosis by enhancing excretion of fluoride. As a laxative, 10-50 grams of tamarind paste as fermented fruit cubes has been used.

Safety

The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Interactions

Interactions with Drugs
Tamarind may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants ("blood thinners") such as warfarin (Coumadin?) or heparin, anti-platelet drugs such as clopidogrel (Plavix?), and non-steroidal anti-inflammatory drugs (NSAIDS) such as ibuprofen (Motrin?, Advil?) or naproxen (Naprosyn?, Aleve?).
Although not well studied in humans, tamarind may lower blood sugar levels. Caution is advised in patients with diabetes or hypoglycemia (low blood sugar), and in those taking drugs that affect blood sugar. Serum glucose levels may need to be monitored by a healthcare provider, and medication adjustments may be necessary.
The fruit pulp may have mild laxative properties, but heat may cause loss of this effect. Caution is advised when combining tamarind with other laxatives due to additive effects.
Concurrent use of tamarind and topical ophthalmic (eye) antibiotics may result in a synergistic effect. Consult with a qualified healthcare professional, including a pharmacist, to check for interactions.
Taking vasoconstrictors and tamarind together may cause a potential additive interaction. Caution is advised.
