Usnic Acid Powder

Product Details

Usnic acid powder comes from the part of Usnea lichen. Usnea is also called Nuluo, Songluo, Longxingcao, Qiancao, Guan Gongxu, Tianpengcao, Shuhang, Songmao, Guoshanlong, etc. It belongs to the lichen door. Filamentous, erect or dangling, gray-white or gray-green, Usnea prefers shady and moist soil, and chooses fertile and loose soil, preferably mountainous and sandy soil with more humus. Grows best in shady and damp places in valleys in hilly or low-mountain areas. Usnea is born on old branches in deep mountains or on alpine rocks, in the form of hanging filaments. Especially in damp forests, epiphytes on conifers. In the dark and humid environment, it grows on the branches of spruce and fir. Born in damp forests, epiphytes on conifers, distributed throughout the country. Usnea is native to the southern United States and central Argentina, and is widely distributed in Central and South America. We mainly offer:

• Beard Lichen Extract 10:1 20:1 50:1
• Usnic acid 98%

Health Benefits

Antibacterial effect: It can effectively inhibit the growth of Gram-positive bacteria such as Staphylococcus aureus, MRSA, Bacillus acnes, Corynebacterium, and can inhibit the growth of Pyrosporidium, directly killing Staphylococcus aureus. cells, hindering the signal transduction pathway of Pseudomonas aeruginosa, suggesting that the extract of Usnea grandis and usnic acid can be used for the treatment of acne, rosacea, seborrheic dermatitis and other related skin diseases; in addition, usnic acid can eliminate sa drug-resistant plasmids.

Antiviral effect: Studies have shown that it has the potential to inhibit the proliferation of mouse polyoma virus, mainly by inhibiting the formation of messenger RNA, thereby indirectly inhibiting the replication of DNA. Usnic acid has the activity of inhibiting Epstein-barrvirus (EBV), of which (+)-usnic acid showed the highest inhibitory activity.

Insecticidal effect: It has the activity of killing the promastigote of Leishmania donovani (Kala-azar), and its in vitro activity concentration is 25μg/mL. Its minimum effective concentration for killing Trichomonas in vitro was 0.4 mg/mL, and there was no significant difference in in vitro killing effects of Trichomonas with the same concentration of metronidazole. It has a growth inhibitory effect on trypanosome larvae at 5-30 μg/mL, and it can also significantly reduce the amount of trypanosomes in the blood.

Anti-tumor effect: Usnic acid has anti-wild-type P53 breast cancer cell line MCF7, but does not cause harm to normal cells, so it is expected to be developed into a new generation of anti-cancer drugs. The inhibitory effect of usnic acid extracted from the fungus Usnea on the proliferation of prostate cancer PC-3M cells in vitro was studied. The cell growth inhibition experiment showed that the maximum inhibition rate was over 80%, and the biological effect was dose-dependent. It can slow down the proliferation of tumor cells and has obvious anti-tumor effect.

Anti-inflammatory activity: The anti-inflammatory activity of usnic acid was studied using the rat foot swelling test (acute inflammation) and the rat cotton ball granuloma test (chronic inflammation), and the anti-inflammatory mechanism and inhibition of usnic acid were speculated. synthesis of prostaglandins.
