Fritillaria is a well-known antitussive drug, and there are many Chinese patent medicines using Fritillaria, such as Chuanbei Loquat Cough Syrup and Chuanbei Qiuli Ointment. At present, there are three kinds of Fritillaria commonly used, namely Fritillaria cirrhosa, Fritillaria thunbergii and Fritillaria thunbergii. Although the names are similar, the functions are quite different, so pay attention when buying. Fritillaria cirrhosa: cough due to deficiency syndrome, slightly cold and sweet. It has strong antitussive and expectorant effects, and has lung moistening effects. It can be used for both phlegm and phlegm, especially for lung dryness and cough. The patient's symptoms are cough, accompanied by scanty sputum, difficulty in coughing, or blood in sputum, dry mouth and nose, dry throat and thirst. At this time, you can choose Bulbus Fritillariae Cirrhosae stewed pear to eat: take Bulbus Fritillariae Cirrhosae 9 ~ 10g, soak it in water, remove the pear core, put the soaked Bulbus Fritillariae Cirrhosae together with water into the hollowed pear, steam it in the pot for one hour, and add a proper amount of crystal sugar to taste before eating. It should be noted that there have been reports of allergies after taking Fritillaria cirrhosa, so people with allergies should use it with caution. Fritillaria thunbergii: If the symptoms of empirical cough are cough, chest pain, aversion to cold and fever, cough with pus and phlegm, dry stool, red tongue and dry mouth, Fritillaria thunbergii should be selected. Fritillaria thunbergii has a stronger fire-purging effect than Fritillaria thunbergii, and is especially good at clearing away fire and dispersing stagnation. It is a good medicine for treating lung abscess. The most commonly used method of Fritillaria thunbergii is: Fritillaria thunbergii 3 ~ 10g, decocted in water once a day. For patients with wind-heat cough accompanied by cough, unfavorable expectoration, yellow and sticky sputum, dry mouth and thirst, and red tongue coating, Fritillaria cirrhosa or Fritillaria thunbergii can be selected. Bulbus Fritillariae Cirrhosae has mild medicinal properties and no strong smell, and is more suitable for the elderly and the weak. Fritillaria thunbergii is the best choice for children and adolescents with strong body heat. At present, Fritillaria cirrhosa is in short supply and the price is relatively expensive. If only "Fritillaria" is indicated on the prescription, most of them are Fritillaria thunbergii, so you should read them clearly when buying them. Although Fritillaria cirrhosa and Fritillaria thunbergii are cough medicines, not everyone is suitable for them. For example, patients with wind-cold cough are accompanied by symptoms such as white fine phlegm, stuffy nose and runny nose, so they should take some drugs to warm the lungs and resolve phlegm. Bulbus Fritillariae Cirrhosae and Bulbus Fritillariae Thunbergii are cold medicines, and taking them at this time is tantamount to adding insult to injury, which will aggravate the condition. Fritillaria thunbergii: detoxification and carbuncle elimination. In addition, Fritillaria is bitter and cold, which is not suitable for children to take for a long time. At present, there have been reports of allergies after taking Fritillaria cirrhosa, so people with allergies should use it with caution.
