Speaking of Fritillaria, a traditional Chinese medicine commonly used in life, many people think of Fritillaria cirrhosa and Fritillaria thunbergii, both of which have the effects of clearing away heat, resolving phlegm and relieving cough. They belong to Liliaceae, and the other one with the same name is Fritillaria thunbergii, which is the dried stem block of cucurbitaceae. It is very different from the commonly used Fritillaria in efficacy and treatment. Fritillaria thunbergii, also known as Fritillaria thunbergii, Sophora flavescens or Fritillaria thunbergii, has a hard texture, is not easy to break, is slightly cold, tastes a little bitter and salty, and can be used for both internal and external use. Produced in Henan, Hebei, Shaanxi, Gansu and other places. Chinese medicine believes that Fritillaria thunbergii has the functions of detoxification, detumescence, hemostasis, convergence and wound repair. In application, it is often used to treat some diseases, such as snake bite, nameless swelling, ulceration, traumatic bleeding and so on. Especially in relieving pain caused by snake venom and insect venom, different swelling and mastitis. When taken orally, it can be directly decocted with clear water, and it is often combined with other drugs to play a stronger role. For external use, Bulbus Fritillariae Thunbergii can be ground into powder, and then mixed with vinegar or water to make paste for external use, which can promote wound healing. In western medicine pharmacology, Fritillaria thunbergii contains maltose, sucrose and reducing sugar, and its efficacy has also been verified. Has antiinflammatory, anticancer, toxic catabolism accelerating, and toxic symptoms relieving effects. Generally, it can be used to treat wound bleeding, mastitis, lymphadenitis, hypertrophic rhinitis, etc. In the folk, some people will directly soak Fritillaria thunbergii in water in order to clear away heat and detoxify. In fact, this is very reasonable and wrong. Although Fritillaria thunbergii has a good effect, it needs to be used according to the doctor's advice, otherwise it will have certain side effects. Mainly because some ingredients in Fritillaria thunbergii will kill male sperm and affect male reproductive ability, so we must pay more attention to it and don't take it without authorization or overdose.
