🌱 What it is
Andrographis paniculata is an intensely bitter plant long used in Ayurvedic and Traditional Chinese medicine, now sold as capsules, tinctures, and standardized extracts.
📜 Where it comes from
Andrographis paniculata has been used for centuries in both Ayurvedic medicine in India and Traditional Chinese Medicine, where it was known as a strong bitter herb for fevers, infections, and liver complaints. It earned nicknames in parts of Asia referencing its use during epidemics of respiratory illness. Western researchers began studying it more closely in the late 20th century for its effects on cold symptoms, bringing it into modern supplement use.
✨ Why it's good for you
- Traditionally used and studied for shortening the length of common-cold symptoms
- May help support comfort during sore throat and cough
- Studied alongside other herbs (e.g., Kan Jang formulas) for upper-respiratory comfort
🥄 How to use it
Take a standardized extract (often 3-6% andrographolide) as capsules or tinctureA concentrated herbal extract made with alcohol. How to make a tincture → at the first sign of a cold, following label dosing. Many people start it right when symptoms begin and use it for a short course of 5-7 days, not continuously.
How much: Follow label directions for a standardized extract (commonly around 400 mg, 1-3 times daily) for up to 5-7 days during a cold, not as a long-term daily supplement.
Why it works: Its bitter compounds, particularly andrographolide, are thought to modestly support the body's immune response, though the exact mechanism is still being studied.
