槲皮素的好处
药理：槲皮素可以驱除痰和止咳，它也可以用作止喘。槲皮素具有抗癌活性，抑制PI3激酶活性并轻微抑制PIP激酶活性，通过II型雌激素受体减少癌细胞生长。槲皮素可抑制嗜碱性粒细胞和肥大细胞的组胺释放。槲皮素可以控制某些病毒在体内的传播。槲皮素可以帮助减少组织破坏。槲皮素也可有益于治疗痢疾，痛风和牛皮癣

护肤领域:
在皮肤护理方面，研究表明，基于脂质的递送系统对于槲皮素发挥抗氧化有益效果是最佳的。
这种类型的配方提供了槲皮素的初始爆发，然后在24小时内持续释放。当槲皮素与硅氧烷和脂质混合时，摄入量更大，通过对人皮肤的测试证实;

槲皮素 可以帮助保护皮肤免受UVB相关的损伤，减少弹性蛋白降解酶的产生，并帮助愈合和改善疤痕的外观

Quercetin benefits
Pharmacology:Quercetin may expel phlegm and arrest oughing, it can also be used as antiasthmatic. Quercetin has anticancer activity, inhibits PI3-kinase activity and slightly inhibits PIP Kinase activity, reduces cancer cell growth via type II estrogen receptors. Quercetin may inhibit histamine release from basophils and mast cells. Quercetin may control the spread of certain viruses within the body. Quercetin may help reduce tissue destruction. Quercetin may also be beneficial in the treatment of dysentery, gout, and psoriasis

Skin care field:
In terms of skin care, research has shown that a lipid-based delivery system is optimal for quercetin to exert antioxidant benefits.
This type of formula provides an intial burst of quercetin followed by sustained release over a 24-hour period. When quercetin is mixed with silicone and lipids, the intake is greater, as confirmed by testing on human skin;

quercetin can help defend skin from UVB-related damage, reduce the production of an elastin-degrading enzyme, and help heal and improve the appearance of scars
