Buchu (Agathosma betulina and Agathosma crenulata) is an aromatic medicinal shrub indigenous to the Western Cape of South Africa. For centuries, it has been used by the Khoi-San people as a powerful natural remedy. The plant is valued mainly for its fragrant leaves, which contain essential oils known for their antiseptic, diuretic, and anti-inflammatory properties.

Buchu is most commonly associated with urinary and kidney health, but its traditional uses extend to joint pain, digestion, skin care, and general wellness.
