Black Horehound
Ballota nigra
Black Horehound (Ballota nigra) is a perennial herb native to the Mediterranean region and parts of Asia. It has dark green, oval leaves and blackish-purple edible flowers. Its odour is described as unpleasant, but its sour, bitter taste is said to be quite pleasant. This hardy and drought-tolerant plant loves sunny areas and grows well in poor soils. It is traditionally used as an ingredient in medicinal teas and as a flavouring agent in food. Its anti-inflammatory, antispasmodic, and expectorant properties make it a popular herbal remedy for treating colds and respiratory conditions.
