Black Catechu Herb – Uses And Side Effects

Black Catechu

Black Catechu was popular in the United States and abroad during the mid 80 and early 1900s. In some parts of the world, people still use it to treat diarrhea and prevent pregnancy.

Black catechu is prepared as a dried extract from the heartwood of Acacia catechu, a tree native to Burma and Eastern India and naturalized in Jamaica . The extract is prepared by boiling heartwood pieces in water, evaporating the mixture to a syrup, and cooling it to molds, which are then broken into pieces.

Don’t confuse black catechu with pale catechu, which comes from a different plant. Pale catechu is used in the dye industry and as a veterinary astringent.

What the research shows

Although black catechu has possible medical uses medical experts can’t recommend it for any condition until they know more about its risks and benefits. The herb hasn’t been clinically tested in humans and its value in treating chronic diarrhea hasn’t been proven. What’s more, researchers don’t know if black catechu is toxic.

Although some women with cracked nipples have used black catechu, scientists don’t know if these women were breast­feeding at the time and thus couldn’t determine whether the herb can harm breast-fed infants.
