Constituent Alterations of Pueraiae Radix and Lacquer Tree Mixture Extract and their Anti-allergic Effects [PDF]
Lacquer has traditionally been used to varnish. Many reports have revealed that lacquer has anti-microbical, anti-cancer, and anti-inflammatory activities. However, urushiol and their derivatives were known as an allergen. Therefore, we expected that lacquer will be used as a good health-food source if its side effect was solved. Here we analyzed their
