Sommaire
What is Reishi?
Origin and History
In Chinese tradition, Reishi is mentioned as early as the Han Dynasty (200 BC). This mushroom grows on the trunks of deciduous trees and is distinguished by its lacquered cap. Ancient texts consider it adaptogenic, capable of helping the body regulate its stress and natural defenses.
Active Components
Its richness lies in polysaccharides, triterpenes, and glycoproteins. Like in an orchestra, these molecules work in synergy: polysaccharides stimulate white blood cells, while triterpenes contribute to respiratory and liver balance.
Reishi Dosage
Recommended Daily Doses
The dose depends on the form and extractivity. In standardized dry extract (10:1 for example), it generally ranges around 300 to 500 mg per day, divided into two doses. In raw powder, it can go up to 1 g to 2 g daily.
| Form | Daily Dose |
|---|---|
| Dry extract (10:1) | 300–500 mg |
| Raw powder | 1–2 g |
| Mother tincture | 2–5 ml |
Pharmaceutical Forms
- Capsules or gel capsules, convenient for precise dosing.
- Powder, to mix in a smoothie or a hot drink.
- Mother tincture, ideal for adjusting the dose drop by drop.
Side Effects and Precautions
Potential Risks
Adverse reactions remain rare: mild headaches, digestive disorders, or skin reactions. In practice, they mainly appear in cases of overdose or in people sensitive to mushrooms.
Drug Interactions
Due to its anticoagulant and hypoglycemic effects, Reishi can potentiate coumarins (warfarin) and diabetes medications. It is therefore better to discuss it with your doctor, especially before surgery or in case of long-term treatment.
Quality criteria for choosing your Reishi
Origin of the mushroom
Favor a product from controlled cultivation, preferably organic. Wild mushrooms can accumulate heavy metals and pollutants.
Type of extract
Check the ratio (10:1, 20:1…) and the percentage of polysaccharides. The more advanced the extraction, the lower the dosage can be to achieve the same effect.
Labels and certifications
The mentions “Organic”, “ISO” or “GMP” guarantee rigorous production. To deepen this point, do not hesitate to consult this comprehensive guide on the mushroom of immortality, rich in practical advice.
