Buchu (Barosma betulina)

Couch Grass (Elymus repens)

About

Buchu is a strongly aromatic, bushy shrub reaching about 6½ ft (2 m), with slightly leathery, dotted leaves that release a distinctive scent. Indigenous peoples of South Africa have long valued buchu as a general stimulant, diuretic, and digestive aid. In contemporary Western herbal medicine, it is prized mainly as a urinary antiseptic and diuretic, traditionally employed for cystitis, bladder infections, irritable bladder, and sometimes prostatitis.

Couch grass is a vigorous perennial growing to 32 inches with a long, creeping rhizome, slender leaves, and erect spikes bearing green flowers aligned in two rows. Found in Europe, the Americas, northern Asia, and Australia, it is an invasive weed harvested throughout the year. In classical times, both Dioscorides (40-90 CE) and Pliny (23-79 CE) recommended couch grass root for poor urine flow and kidney stones. The herbalist John Gerard wrote in 1597 that 'Couch-grasse be an unwelcome guest to fields and gardens, yet his physicke virtues do recompense those hurts; for it openeth the stoppings of the liver and reins [ureters] without heat.' In times of famine, the root was roasted and ground as a substitute for coffee and flour.

Safety & precautions

Dryness & Acute Inflammation: Not recommended if dryness predominates or if there is active, acute inflammation of the urinary tract. Children Under Two: Generally contraindicated for very young children. Pregnancy: Because buchu contains pulegone (a uterine stimulant), it should be avoided during pregnancy unless advised by a qualified healthcare practitioner. High Dosages: Potentially toxic in excessive amounts.

Generally safe. No known warnings for normal use.
