A hard, woody polypore with a golden interior grows on the living trunks of mulberry and other deciduous trees: Phellinus linteus, known in China as sanghuang and in Korea and Japan by related names. For over two thousand years, traditional East Asian medicine reserved it for cases considered most serious, and this ancient reputation is now one of the drivers of its scientific research.
Main Active Compounds
- Polysaccharides and proteoglycans, especially beta-glucans, considered its main immunomodulatory agents.
- Hispidin and polyphenolic derivatives, responsible for a good part of its antioxidant activity.
- Flavonoids, phenolic acids, and triterpenoids.
Scientifically Documented Effects
Dialogue with the Immune System
Most research has focused on its polysaccharides, studied for their ability to activate immune cells and modulate their response. This immunomodulatory pattern is the trait that contemporary science has most explored and that supports its role in supporting the body's defenses.
Antioxidant Activity
Hispidin and other sanghuang polyphenols show a strong ability to neutralize free radicals, which helps maintain balance against oxidative stress.
Metabolic Research
More recent lines of work explore its relationship with glucose metabolism, within the general study of medicinal mushrooms as support for a balanced metabolism.
How to Take It
Due to its woody texture, it is not consumed as food: it is used in prolonged decoctions or, more frequently today, as a concentrated extract in powder or capsule form. The standardization of beta-glucans is a good indicator of quality.
Precautions
As a potent immunomodulator, caution is recommended for people with autoimmune diseases or those receiving immunosuppressants, as well as during pregnancy and lactation. Consult with a healthcare professional before incorporating it.
