Buchu

Background

Buchu is a plant from South Africa. The leaf is used to make medicine.

Buchu is used for urinary tract infections (UTIs), including infections involving the urethra (urethritis) and kidneys (pyelonephritis). It is also used by mouth for treating inflamed prostate (prostatitis), benign prostatic hyperplasia (BPH), high blood pressure, fever, cough, common cold, upset stomach, stomach ulcers, irritable bowel syndrome (IBS), gout, and sexually transmitted diseases (STDs).

Buchu is applied to the skin as an insect repellant, as a deodorant, and for skin infections.

In manufacturing, the oil from buchu is used to give a fruit flavor (often black currant) to foods. It is also used as a fragrance in perfumes and colognes.
Buchu is LIKELY SAFE in food amounts and POSSIBLY SAFE when used as a medicine. But it is POSSIBLY UNSAFE in larger amounts and when the oil is consumed. Buchu may irritate the stomach and kidneys and increase menstrual flow. It may also cause liver damage.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Don’t use buchu in amounts that are larger than usual food amounts if you are pregnant. Buchu is LIKELY UNSAFE when taken during pregnancy. There have been reports linking buchu to miscarriages.

If you are breast-feeding, buchu is POSSIBLY SAFE in food amounts, but don’t take larger amounts. Not enough is known about the safety of buchu during breast-feeding.

Bleeding disorders: Buchu might slow blood clotting and increase bleeding. In theory, buchu might make bleeding disorders worse.

Kidney infections: Even though some people use buchu for kidney infections, health experts advise against this.

Liver problems: Large amounts of buchu may cause liver problems, even in healthy people. Therefore, people with a history of liver problems should avoid buchu. Taking a large amount of buchu might make liver disease worse.

Urinary tract inflammation: Don’t use buchu if you have pain and swelling in the urinary tract.

Surgery: Buchu might slow blood clotting. There is some concern that it might increase the risk of bleeding during and after surgery. Stop using buchu at least 2 weeks before a scheduled surgery.
