Why You Need It

- Neurological Calming: Used historically to calm 'internal wind' (convulsions or tremors).
Deep Dive
Japanese Arisaema is a heavy hitter in the world of herbal medicine. Its primary mechanism is acting as an expectorant and anti-inflammatory agent. In clinical settings, processed Arisaema is often combined with other herbs to treat bronchitis, coughs, and lymph node inflammation. The active compounds, specifically calcium oxalate raphides and saponins, are responsible for its numbing and swelling-reducing effects. However, because the raw plant is highly irritating to the digestive tract and skin, it is strictly a medicinal herb used in formulae, not a daily supplement.
Natural Food Sources
CRITICAL: Japanese Arisaema is NOT a food source. It is a toxic tuber that must be detoxified before use. Unlike Vitamin C found in oranges, this is a medicinal root.
Supplementation
- Dosage: Typically 3-6 grams of processed root in decoction, or in pill form as prescribed by a TCM practitioner.
- Who should take it: Those with specific diagnoses of 'Phlegm-Heat' or 'Wind-Phlegm' obstructing the channels.
- Usage: Do not consume raw. It must be cooked with ginger or processed with sulfur to reduce toxicity.
