Catechu is an herbal extract that is derived from the Acacia catechu tree, which is native to parts of Asia and Africa. The herb has a long history of use in traditional medicine, particularly in Ayurvedic medicine, and is known for its astringent properties.

The active compounds in catechu include tannins, flavonoids, and catechin, which are believed to contribute to its medicinal properties. In traditional medicine, catechu has been used for various purposes, including as an antidiarrheal, antiseptic, and anti-inflammatory agent.



  • Digestive health: Catechu is believed to have astringent properties, which means that it can help tone and tighten the tissues in the digestive system. It may be useful for treating conditions such as diarrhea, dysentery, and other digestive disorders.

  • Oral health: Catechu is believed to have antimicrobial and anti-inflammatory properties, which may make it useful for promoting oral health. It may be used as a mouthwash or added to toothpaste to help prevent gum disease and other oral infections.

  • Skin health: Catechu is also used in traditional medicine to promote skin health. It is believed to have anti-inflammatory properties that can help soothe skin irritation and inflammation. It may also be useful for treating conditions such as acne, eczema, and psoriasis.



  • Catechu can interact with certain medications, including blood thinners and medications for high blood pressure, and should not be used by people taking these medications without first consulting a healthcare provider.

  • Catechu can cause gastrointestinal symptoms, such as nausea, vomiting, or constipation, in some people.

  • The safety of using catechu during pregnancy and breastfeeding has not been fully studied, and it is best to consult with a healthcare provider before using it during these times.

  • Catechu may cause allergic reactions in some people, particularly those who are sensitive to tannins.

  • Catechu can cause staining of teeth and should be used with caution by people who are concerned about dental health.


Tastes LIke:

Catechu, also known as Acacia catechu or black catechu, is typically consumed as a component of traditional herbal remedies, and as such, it does not have a distinct taste or flavor.

In some cases, catechu may be included as a component of a larger herbal tea or formula, which can have a range of flavors depending on the other herbs included in the mixture. In these cases, catechu is believed to have a slightly bitter and astringent taste.



  • Decoction: A decoction is a strong tea made by boiling herbs in water. To prepare a decoction that includes catechu, place the prescribed amount of the herb and other ingredients in a pot with water, bring to a boil, and simmer for 20-30 minutes. The mixture is then strained and consumed as directed.

  • Powder: Catechu may also be ground into a powder and added to other powdered herbs to create a customized formula. The powdered herbs can be mixed with water to create a tea or taken directly in capsules or pills.

  • Topical application: Catechu is sometimes used topically to promote skin health. In these cases, it may be combined with other herbs and applied directly to the affected area as a paste or poultice.
