Avoid spicy and stimulating diet during the period of taking the medicine. Explanation: Prolonged cough is a very common clinical condition. He Fudong believes that the cause of prolonged cough is mainly due to Yang deficiency and inability to expel evil, wind and phlegm staying in the lung for a long time, and contracture of the airway. After treatment, most of the cold and heat evils have been removed, but wind evils are alone, and the patient’s yang energy has been injured, so he is unable to drive away the evils; some patients have a biased physique (especially allergic physique), so newly induced external evils (wind-cold and wind-heat) can be easily induced to dry up the lung system, and the lung loses publicity and purification, so the prolonged cough persists. Phlegm is a thing, it is born from the coalescence of fluids; the lung loses publicity and purification, the fluids are not distributed, and the fluids condense into phlegm. The wind and phlegm fight with each other, and the evidence of this disease is caused by the internal lodging in the lung. Phlegm as a thing, can be tangible phlegm, such as coughing up phlegm; can also be invisible phlegm, phlegm, phlegm signs, such as light tongue, thin white or slightly greasy coating, fat tongue with teeth marks, smooth pulse, etc. for phlegm signs. The wind and phlegm are internalized in the lung and the lung qi is rebellious, so we can see cough and phlegm; the wind prevails and itches, so we can see throat itching and coughing bouts. In the formula for prolonged cough, Ephedra, Radix et Rhizoma, and Hesperidin are the rulers. Ephedra, Radix et Rhizoma, and Hesperidin are from the Treatise on Typhoid and Shao-Yin Diseases, which treats Shao-Yin diseases and superficial symptoms. Ephedra is an essential medicine for the lung meridian, promoting the lung to stop cough and dispersing the evil of the sun on the surface; Pieces of Ephedra enter the kidney meridian, benefiting the kidney and warming the yang, supporting the righteousness and dispelling the evil; the combination of Ephedra and Pieces of Ephedra warms the lung to stop cough and helps the yang to publish; the pungent, warm and masculine pungency warms the lung to dissolve drinks and disperses wind and cold, in combination with Ephedra, strengthens the function of warming the meridian and dispersing the cold to open the orifices, and in combination with Pieces of Ephedra, has the effect of warming the Shao Yin, helping the yang to dispel the cold and warm the lung. The three herbs are used together to warm the Yang of Shao-Yin internally and the surface of the Sun externally, helping to dispel the evil, relieving the surface in warming the meridians and warming the Yang in relieving the surface, so that the lungs and kidneys have mutual roots and the son fills the mother’s qi, thus treating Yang deficiency and wind cough. Cicada molasses, scorpion, silkworm, dilong, centipede search the wind, relieve spasm and cough, white hair Xia Gu Cao to lower the gas and stop cough; Gui Zhi and dry ginger imitate the meaning of Xiao Qing Long Tang to warm the lung and dissolve the drink; long cough is bound to deplete the lung qi, use Wu Mei and Wu Wei Zi to astringent the lung and stop cough as adjuvant medicine, and a large number of Wu Mei and Wu Wei Zi with ephedra and saposhnikin and five worms can prevent the disadvantages of the ruler and minister too pungent. Glycyrrhiza glabra is a harmonizer of all the medicines, it can slow down the dryness of hemp, gui and many insects, and it is an antidote to the toxicity of pungent and fenugreek. The whole formula is ascending and descending because of each other, dispersing and collecting in a proper way, which is clinically tested and has definite curative effect.
