Agathosma betulina

Buchu

Rutaceae

Native to the Western Cape of South Africa, where it grows wild in the mountainous regions of the fynbos biome. Prefers well-drained, sandy soils and sunny exposure. Now cultivated in small quantities elsewhere, though most commercial Buchu is still wild-harvested or sustainably grown in its native range.

A small, shrubby evergreen plant with shiny, rounded, leathery leaves and small, star-like white or pale pink flowers. The leaves are highly aromatic — with a distinctive scent that is somewhere between blackcurrant, rosemary, and peppermint. Crushed leaf is intensely fragrant and medicinal.

Traditionally used as a urinary tract antiseptic and diuretic — especially in infections like UTIs, cystitis, and prostatitis. Helps flush the urinary system while also reducing inflammation and easing irritation. Can also be used for water retention and some digestive complaints. Used externally in wash form for bruises and sprains. In traditional Cape medicine, it was used as a general tonic and cleansing herb.

Warming, drying, aromatic. Moves stagnation in the urinary system and can uplift mood when used in small doses. Feels sharp and clean — a “scrubbing” sort of energy.

Leaf (dried)

Volatile oils (primarily diosphenol), flavonoids, mucilage, resins, and a small amount of alkaloids. The oil content is responsible for much of its antiseptic action.

Use Buchu primarily for irritated or “hot” urinary tract issues — especially when there’s burning, discomfort, or chronic tension in the bladder. It pairs well with marshmallow root to balance its dryness. While rarely used alone, it’s a strong and reliable ally in UTI blends. The scent is incredibly unique — uplifting, sharp, and almost citrusy. It’s been found to have a subtle mood-lifting effect when someone feels damp, stuck, and irritated (especially in the pelvic region).

• Leaves are harvested when mature and highly aromatic, usually in summer. • Must be dried carefully to preserve volatile oil content. Most commonly sourced from South African growers.

Not for use in pregnancy or kidney inflammation. High doses or extended use can irritate the kidneys. Use with caution in people with sensitive or dry constitutions. Always balance with demulcent herbs if dryness is present.
