Respiratory symptom support (traditional)

Mixed Evidence

Traditional European use only; modern controlled human evidence is essentially absent.

How it works

Hempnettle contains silicic acid, iridoid glycosides, and tannins. Traditional use targets the upper respiratory tract as a mild expectorant. The silicic acid content has been suggested as supportive for connective tissue, though clinical evidence is lacking. Use has declined in modern Western herbalism, and clinical evidence is essentially absent.

Dosage

Traditional doses use 1.5 to 3 g of dried herb in tea, multiple times daily. Tincture doses are 2 to 4 mL.

When and how to take it

Traditional preparations are taken with the onset of respiratory symptoms.
