Is Pinellia ternata poisonous?

Traditional Chinese medicine Pinellia ternata, "raw products are toxic, cooked products are non-toxic". Any internal service must be made into the square with processed products. Therefore, in the ancient medical literature, the processing technology of Pinellia ternata and the efficacy of different processed products have been recorded as an important part of standardizing the quality of traditional Chinese medicine.

The medicinal processed products of Pinellia ternata were first seen in "treating Pinellia ternata" in the Internal Classic of Huangdi, but there is no detailed processing method of "treating Pinellia ternata". The processing method of Pinellia ternata was clearly recorded in the Jingui Jade letter Classic written by Zhang Zhongjing in the Han Dynasty. The method of soup washing has been used since the Han Dynasty. (note: soup to wash an ancient Pinellia ternata must be washed with boiling water seven times to ensure safe use. Pinellia ternata used in modern clinic has been concocted, so there is no need to operate it by yourself. )

2. The processing method of Pinellia ternata

Liang Dai Tao Hongjing's "Collection of Materia Medica Classic" expounds the processing method and purpose of Pinellia ternata in more detail and clearly: "Pinellia poison, use ginger juice, boil ginger juice and solve it." In the story, Sun Simiao's "Jiang Tang Jie Pinellia toxin" is the practical application of "fear each other and kill each other to make Pinellia ternata". Therefore, "making Pinellia ternata with ginger" is a major breakthrough in addition to "soup washing". It makes the processing of Pinellia ternata develop from simple soaking and detoxification to according to the theory of mutual fear and killing in traditional Chinese medicine, adding other processing excipients to restrict its toxicity.

After the Tang Dynasty, the excipients for processing Pinellia ternata also expanded from single ginger to other excipients, such as alum, soap horn, licorice, head vinegar (unmixed vinegar), white mustard seed and so on, in order to meet the different needs of clinical treatment. It can be seen that the processing technology of Pinellia ternata has developed to use different excipients to concoct Pinellia ternata on the basis of "adding excipients and removing its toxicity", so as to give it new medicinal properties and efficacy.

In addition, the efficacy and main treatment of Pinellia ternata processed with different excipients are different, for example, the excipients used in Pinellia ternata are licorice and quicklime, which have the effect of dryness and dampness and resolving phlegm, which are mostly used in phlegm, cough and asthma, etc.; ginger and alum are used as excipients in ginger and alum, which are used to resolve phlegm in temperature and are mostly used for phlegm drinking and vomiting. Therefore, in the specific clinical use, must be treated differently.
