There are many herbs to cleanse the lungs and detoxify the body. You can choose herbs that are light in texture, easy to seep out and not too bitter in taste to be used to make water to drink. For example, Luo Han Guo, Mai Dong, Sha Shen, Western Ginseng, Wild Chrysanthemum, Honeysuckle, Fat Sea, etc. You can choose one alone or use two or more in combination. It is best to use just-boiled boiling water when making herbal infusions, as this makes it easier for the herbal medicine to ooze out the flavor. The water is suitable for patients with yin deficiency and dry mouth, and can play a role in clearing heat and quenching thirst. Fatty sea is very effective for sore throat and hoarseness caused by wind-heat, usually three or four pills at a time will do. Mai Dong Sha Shen with water is good for dry lung cough. Wild chrysanthemum and honeysuckle are very effective in clearing heat and detoxifying the toxins for patients with coughs with yellow phlegm where heat toxicity is obvious.
