【Formula Explanation】

《Han Dian》: This formula has a complex composition. Asparagus Root (Tian Men Dong), Ophiopogon Root (Mai Men Dong), Schisandra Fruit (Wu Wei Zi), etc., moisturize the lungs, clear lung heat, and moisten dry phlegm, making it easier to expectorate. Fritillaria Bulb (Bei Mu), Apricot Kernel (Xing Ren), Mulberry Bark (Sang Bai Pi), Platycodon Root (Jie Geng), Dried Tangerine Peel (Chen Pi), Poria (Fu Ling), etc., assist in resolving phlegm. Scutellaria Root (Huang Qin) and Gardenia Fruit (Shan Zhi Zi) primarily reduce heat in the chest. Angelica Sinensis (Dang Gui) and Licorice Root (Gan Cao) nourish the blood and alleviate rebellious Qi. Although the symptoms treated by this formula are similar to those for <a href='https://whatsintcm.com/dt_articles/Ophiopogon Root (Mai Men Dong) Decoction/’>Ophiopogon Root (Mai Men Dong) Decoction, the difficulty in expectorating phlegm is not as severe as the intense thirst in Ophiopogon Root (Mai Men Dong)‘s indications, and the phlegm is more abundant, with less severe rebellious Qi.

 【Functions】

Clearing lung heat, resolving phlegm, relieving cough.

 【Therapeutic Actions】

All types of cough, especially those with abundant phlegm in the upper jiao, persistent severe cough with copious, thick, sticky phlegm that is difficult to expectorate, and chronic intractable cough.

 【Indications】

Chronic bronchitis, chronic pharyngitis, pneumonia, pulmonary tuberculosis, bronchiectasis, bronchial asthma, cardiac asthma, and other related conditions.
