Can its merit be merely discussed in terms of dispelling Wind?
In Shanghan (Cold Damage) headache, if the pathogen has not yet entered the Yangming channel, it is contraindicated. For Five Exhaustions and Seven Injuries, or conditions with Excess above and Deficiency below, even if there are Spleen-Stomach diseases during the hot months, it should not be taken.

Because its efficacy is similar to Maidong, it is also called Mendong.
The flavor is bitter, sweet, and slightly acrid; the nature is Cold. The flavor is strong while the aroma is faint; it belongs to Yin within Yang. It enters the Qi aspect of the Hand-Taiyin Lung Channel and Foot-Shaoyin Kidney Channel. It mainly treats dryness by moistening and nourishing Yin.

It is said: Generally, when disease arises from Yin Deficiency and water depletion, with Fire rising from the Lower Jiao and flaming up to the Lung, causing Phlegm and wheezing, Tiandong is indeed a crucial herb.

They are naturally opposite. Regarding the Root/Branch theory, I do not know what the insight is.
Taking it alone will certainly cause loose stools, due to its cold and moistening/laxative nature. (Li Shizhen)
[Processing] Select those that are plump, round, large, and have a sweet taste. Soak in decoction, peel, remove the heart, bake until hot, then cool in the wind. Repeat this two or three times until naturally dry.
