It also means quercetin acts as an antihistamine leading to relief of allergies and asthma.       Product Name:：Sophora Japonica Extract Quercetin                       Active Ingredient:  Quercetin Powder         Specification:  95% , 98% HPLC         Appearance: Yellow fine powder         CAS  Number: 117-39-5…
