(1) Almond

Ingredients: The seeds contain about 5% fatty oil and 2% amygdalin. The latter can generate hydrocyanic acid, benzaldehyde and glucose after hydrolysis. In addition, it also contains amygdalase, amygdalinase and cherry glycoside enzyme.

Meridian distribution of nature and flavor: bitter, lukewarm, slightly toxic. Returns to the lung and large intestine meridians.

Effects: Relieving cough and asthma, moistening intestines and laxative. After the therapeutic dose of this product is taken orally, its active ingredient amygdalin is slowly hydrolyzed in the body and gradually generates trace amounts of hydrocyanic acid. The latter has a sedative effect on the respiratory center, quieting respiratory movements and exhibiting antitussive and asthmatic effects. .

It is a commonly used traditional Chinese medicine for relieving cough and asthma.

Adverse reactions: Taking too much may lead to poisoning, ranging from dizziness and vomiting to coma, convulsions, respiratory disorders, and mydriasis.

Meridian distribution of nature and flavor: bitter, flat. Returns to the lung and stomach meridians.

Function: Clears the lungs and resolves phlegm, relieves cough and asthma. Because it contains amygdalin, its effect is similar to that of bitter almond. After oral administration, it decomposes trace amounts of hydrocyanic acid, which has a certain antitussive effect. The oil contained in it has a mild expectorant effect. The water decoction of this product has antibacterial, antiasthmatic and expectorant effects through animal experiments.

Ingredients: Contains a variety of alkaloids such as tuberculine and protopodine.

Meridians of nature and flavor: sweet, bitter, flat. Returns to the lung meridian.

Effects: Moisten the lungs and relieve cough, kill lice and insects. Pharmacological experiments have shown that Rhizoma Rhizoma can reduce the excitability of the respiratory center and inhibit the cough reflex, thereby producing an antitussive effect. It is a central antitussive.

Antibacterial tests show that it has certain antibacterial effects on Mycobacterium tuberculosis, Bacillus diphtheriae, Staphylococcus aureus, hemolytic Streptococcus, and Diplococcus pneumoniae. Animal experiments have shown that this product has a preventive and therapeutic effect on Asian influenza A virus infection.

(4) Pinellia ternata

Ingredients: Contains β-sitosterol and its glucoside, 3,4-dihydroxybenzaldehyde glucoside and its aglycone, 2,5- Dihydroxyphenylacetic acid, the last two are irritating substances of Pinellia ternata, in addition, they also contain pungent alcohol, triterpene alcohol, etc.

Meridian distribution of nature and flavor: pungent, warm, poisonous. Returns to the spleen, stomach and lung meridians.

Function: drying dampness and reducing phlegm, lowering Qi and stopping vomiting, eliminating pimples and dissipating stagnation. Pharmacological experiments show antitussive, antiemetic and vomiting (raw Pinellia ternata) effects. The antitussive effect is slightly inferior to that of codeine phosphate.

Meridian distribution of nature and flavor: bitter, cold. Returns to lung and heart meridian.

Function: Relieving cough and reducing phlegm, clearing away heat and dissipating stagnation. Pharmacological experiments have shown that zhebeine has obvious antitussive effects and bronchial smooth muscle relaxation effects. Its antitussive mechanism may be related to bronchial smooth muscle relaxation. Fritillary Fritillaria is clinically used to treat coughs caused by wind-heat cold, acute upper respiratory tract inflammation, tracheitis, and pneumonia. Compared with Fritillaria Fritillaria, Fritillaria Fritillaria is suitable for acute wind-heat cough, while Fritillaria Fritillaria is suitable for chronic fatigue cough.

(7) Fritillary fritillary

Ingredients: Mainly include alkaloids such as fritillary alkaloids, fritillary alkaloids, and fritillary alkaloids.

Meridian distribution of nature and flavor: bitter, sweet, slightly cold. Returns to lung and heart meridian.

Function: Clear away heat and moisturize the lungs, relieve cough and reduce phlegm. As an antitussive and expectorant drug, it is mainly used for coughs with no or little phlegm. However, Sichuan Fritillaria can both eliminate phlegm and inhibit the secretion of phlegm and saliva, so it is also suitable for people with a lot of phlegm.
