1. Origin and description

Purple Adenosma refers to the dried stems, leafy branches and flowers of the plant, traditionally collected, sun-dried or gently dried for herbal use. It belongs to the Plantaginaceae family. In Vietnam, it is also known as ‘Nhân trần Tây Ninh’ because it was once recorded growing abundantly in some southern areas, especially dry fields, wasteland and warm-climate regions.

This is an aromatic herbaceous plant. When crushed, the plant releases a clear herbal fragrance. The stem is often branched, the leaves grow opposite each other, and the leaf blades are small with lightly serrated edges. The flowers are purple or pale purple and usually grow in clusters at the tips of branches. After drying, the herb ranges from brownish green to purplish brown, with a slightly pungent aroma and a spicy, mildly bitter taste.

A key identification feature of this herb is its essential-oil aroma. Good-quality Purple Adenosma should be evenly dried, free from mold, and still retain its natural color. It normally includes a mixture of stems, leaves and flowers. When decocted, the liquid has a gentle fragrance and a light bitter taste that is usually easy to drink.
