Buchu is a plant native to South Africa, known for its aromatic leaves that have been used for centuries in traditional medicine. The leaves are often dried and used to make herbal teas or extracts, which are believed to have various health benefits, including anti-inflammatory and diuretic properties. The two main species of buchu are Agathosma betulina and Agathosma crenulata. These plants thrive in the fynbos biome and are characterized by their small, star-shaped flowers. Buchu is also popular in the cosmetic industry for its fragrance and potential skin benefits.
