3. Biological Functions of the Extract

• Immune System Modulation: As mentioned earlier, the Phellodendron amurense extract, particularly berberine, has the potential to modulate the immune system. It can regulate the activity of immune cells such as macrophages and lymphocytes. In autoimmune diseases, where the immune system attacks the body's own tissues, the extract may help to restore the balance of the immune response. For example, in rheumatoid arthritis, it may reduce the excessive inflammation caused by the overactive immune system.
• Antimicrobial Activity: The antimicrobial properties of the extract are due to its various components, especially alkaloids like berberine. It can inhibit the growth of a wide range of bacteria, including Gram - positive and Gram - negative bacteria. This makes it a potential natural alternative to synthetic antibiotics. In addition to bacteria, it also has antifungal activity, which can be useful in treating fungal infections such as athlete's foot and candidiasis.
• Antioxidant Effects: The flavonoids and other antioxidant components in the extract scavenge free radicals. By reducing oxidative stress, it can protect cells from damage and may slow down the aging process. It may also be beneficial in preventing diseases related to oxidative stress, such as cataracts, macular degeneration, and certain types of cancer.
• Anti - inflammatory Activity: The extract can inhibit the production of inflammatory cytokines and mediators. This anti - inflammatory effect can be beneficial in various inflammatory conditions, from skin inflammation to internal organ inflammation. For example, in skin diseases like eczema and psoriasis, it may reduce redness, itching, and swelling.
