Natural |
|
Inhibits the formation of fungal hyphae, sputum, and spores by interfering with the biosynthesis of chitin in the cell wall of pathogenic fungi, and blocking the spread of disease. It also induces crops to produce anti-retroviral reactions |
|
Extracted from the root of Rhubarb, lichen pigments and various plant seeds. It also occurs naturally in Alternaria porri, Cortinarius canarius, and some other organisms |
|
Physcion is often produced by extracting it from the roots and stems of Chinese rhubarb (Rheum palmatum) using conventional phytochemical separation techniques |
