Although Anemarrhena asphodeloides can nourish yin and moisten dryness, the bitter and cold herbs should only be rich in heat syndrome and should not be misused.

Anemarrhena rhizome is called "bitter, sweet and cold" in Chinese medicine textbooks, but it is only called "bitter and cold" in Shennong Herbal Classic, without the word "sweet". Judging from its efficacy, it can really nourish yin and moisten dryness without adding a word "sweet".

Anemarrhena asphodeloides has the effects of clearing away heat and purging fire, nourishing yin and moistening dryness, entering the lung, stomach and kidney meridians, clearing fire from the lung, stomach and kidney meridians, and nourishing lung, stomach and kidney yin. Therefore, although they are all bitter and cold, they are different from Coptidis Rhizoma, Scutellariae Radix and Cortex Phellodendri. Three yellow and bitter dryness have the disadvantage of damaging yin, but Anemarrhena asphodeloides has no such disadvantage.

According to the classics, Anemarrhena asphodeloides "cures thirst, heat, eliminates evil spirits, causes edema of limbs, enters water, tonifies deficiency and benefits qi".

Anemarrhena asphodeloides is cold and damp, and "quenching thirst and warming the middle warmer" is its right treatment.

How to understand "exorcism"? All evil spirits can be described as evil, so it has a wide range. Combined with the taste of Anemarrhena asphodeloides, it must refer to the evil of dryness and heat.

"Limb edema" is most closely related to lung, spleen and kidney. Lung governs the movement of water, spleen governs the transport of water and fluid, and kidney governs water. How does Anemarrhena treat limb edema? Zhang Xichun explained that "the edema of the main limb will disappear by itself because of its cold and slippery", and Zhang also said that "Anemarrhena asphodeloides clearing away heat and relieving bitter cold will disappear by itself, instead of spleen yang deficiency and kidney water overflowing". Therefore, it is known that the mother treatment of edema acts on the lungs and is used to treat edema caused by abnormal lung heat and unfavorable waterway. However, it is rare to treat edema with Anemarrhena asphodeloides in clinic.

It is the easiest to misunderstand "tonifying deficiency and benefiting qi". Ye's Classic Interpretation of Materia Medica says that "those who benefit qi, bitter cold also benefits the yin of the five internal organs", which is completely unreasonable. How to make tonic for products attacked by bitter cold? Anemarrhena asphodeloides has no direct effect on invigorating qi, and it is also different from ginseng's yin of "nourishing the five internal organs". This sentence in the Classic can be understood as "clearing pathogenic factors with heat and strengthening the body resistance", that is, "eliminating pathogenic factors means strengthening the body".

Although Anemarrhena asphodeloides is sweet and moist, it is bitter and cold after all, and is only suitable for treating real fire. For example, it can be used to treat Yang Ming's excess heat with symptoms of excessive heat, excessive sweating, polydipsia, and heavy pulse. Combine with gypsum to form white tiger soup; For cough due to lung heat, symptoms such as cough, thirst and yellow sticky phlegm are equivalent to Scutellaria baicalensis Georgi, Fritillaria Fritillaria and Fructus Trichosanthis, such as Jinqing Huatan Decoction; It can be used for treating deficiency fire, hot flashes, night sweats, vexation, insomnia, etc. It is combined with Cortex Phellodendri and White Dihuang Pills.

As for the syndrome of intestinal dryness and constipation, it is most suitable for lung and stomach heat to cause body fluid damage. If the body fluid is insufficient, Anemarrhena asphodeloides can't be reused, so as to avoid the syndrome that bitter cold hurts spleen yang. Therefore, it is not suitable for people with spleen and stomach deficiency and cold stools. The famous doctor Bielu is also called "taking one more dose is a laxative", so we should pay attention to it.

Regarding the bitter cold of Anemarrhena asphodeloides, Zhang Xichun thought that it was not bitter cold. He said in "Chinese Medicine Trial": "Anemarrhena asphodeloides is neither cold nor bitter. If you taste it and use it equally with Astragalus membranaceus, you won't feel cold or hot at all, and its nature is not known by Great Cold. It is also cooked with one or two pieces of Anemarrhena asphodeloides and two pieces of licorice, that is, sweet is better than bitter, and the taste is not big. " This is Zhang's experience and can be used for reference. However, in actual clinical work, we should be cautious in syndrome differentiation and use acupoints mainly based on excess heat to avoid making waves.
