Ban Lan Gen is China's household cold-season defender — the root that became a national phenomenon as granule sachets in every pharmacy. Bitter and cold, it powerfully clears heat-toxin and cools the blood, particularly for sore throats and epidemic heat conditions at their start.
🌿 Действия
- •Clears heat and resolves toxicity
- •Cools the blood and benefits the throat
- •Disperses swellings
📖 Применение
9–15 g in decoction; short courses only (3–5 days) given its cold nature.
🔬 Современные исследования
Indigotindisulfonic acid and isatis alkaloids are studied for antiviral activity; ban lan gen remains a fixture of Chinese influenza-season practice.
⚠️ Противопоказания
Avoid with spleen-stomach deficiency cold; prolonged use injures digestion. Not for cold-type illness.
