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

It is thought that the active chemicals in buchu may kill germs and also promote urine flow [1].
