This poem not only explains the growth time and preparation method of Pinellia ternata, but also understands its efficacy in treating phlegm and dampness and the contraindications of its use.

According to the third edition of the Taiwan Chinese Pharmacopoeia, Pinellia ternata (http://en.whatsintcm.com/dt_articles/%e5%8d%8a%e5%a4%8f/) is a species of the Araceae plant Pinellia ternata (Thunb.) Breitenb. Dried tubers, and the Pharmacopoeia has also included raw Pinellia ternata in the “List of Highly Poisonous Traditional Chinese Medicines” to remind the public to be careful when using it. Its medicinal materials are mainly produced in Sichuan, Hubei, Hunan, Anhui and other places, among which the quality produced in Sichuan is better. It is also produced in South Korea and Japan, and is cultivated sporadically in Taiwan. It is also known as Diwen, Shoutian, Shigu, etc. It is also called Shuiyu because its shape is like jade, and it is also called Sheep Eye Half because its medicinal material looks like a sheep’s eye. In summer, it usually has three leaves when it grows, so it is also called the three-leaf Pinellia ternata. In the “Book of Rites and Moon Order” it is recorded: “The Pinellia ternata is born in May and covers half of the summer, hence the name.” Usually after harvesting in summer and autumn, the skin and fibrous roots are washed and dried in the sun for later use. The medicinal materials are spherical in shape, with a white or light yellow surface, and have the characteristics of “dimples” with sunken stem marks at the top of the rhizomes. There are many “brown eyes” or “pockmarks” of fibrous root marks around the base of the stem. They are large in size, hard in texture, white in cross-section, rich in powder, and taste numb, pungent, and irritating to the throat. The medicinal materials that are easily confused among the public include the rhizomes of Tiger Palm (Pinellia ternata) or the tubers of Pinellia ternata. In the past, sometimes because of the high price of medicinal materials, the tubers of the same Araceae taro were used and processed into round or round shapes. It is used in round slices, so be careful when purchasing medicinal materials.

  This medicinal material was first recorded in the “Shen Nong’s Materia Medica” and was listed as a lower grade. It is recorded in “Bielu of Famous Doctors”: “It is slightly cold when raw, warm when cooked, and is poisonous. It is mainly used to eliminate phlegm-heat in the heart, abdomen, chest, diaphragm, and phlegm-heat, cough, shortness of breath, and heartburn. Pain, hardness, vomiting, carbuncle swelling, miscarriage, impotence and yellowing. It makes people vomit when raw, and makes people vomit when cooked. “It shows that in addition to the toxicity of the medicine, the processed medicinal materials have good effects on antivomiting. Effect. The medical sage Zhang Zhongjing is also good at using Pinellia ternata, and many prescriptions also use Pinellia ternata. For example, Banxia Xiexin Decoction, Banxia Houpu Decoction, Xiaobuihu Decoction, etc., which shows its importance.

  According to different clinical uses, there are several different ways of preparing it: the clear Pinellia ternata is mainly soaked in water with alum and raw Pinellia ternata. After two weeks, the water will turn white, and the water should be changed again after two weeks. The thick alum water is soaked for another week, and then boiled to make the white heart disappear and there is no numbness in the taste. After that, it can be dried and stored for later use. In addition, some ginger or licorice will be added to prepare it. Another type of medicine mainly used to relieve vomiting is ginger pinellia. The main method of preparing it is to soak raw pinellia in ginger juice for 5 days, then change the water and then soak until the white flakes disappear in the water. When the taste does not numb your tongue, pick it up and put it in again. For ginger juice, simmer it over medium heat for 4 to 6 hours and then dry it in the sun for later use. Alternatively, you can also prepare it with licorice and ginger. The other method is French pinellia. Take pinellia ternata, separate the sizes, soak in water until there is no dry core inside, take out an appropriate amount of licorice, add water and boil it twice, combine the decoctions, and pour into the lime liquid made with an appropriate amount of water. , stir well, stir 1-2 times a day, until the cross section is uniformly yellow and tastes slightly numb, take it out and wash it for later use. There is also a method of preparing Banxia koji, which was mainly made by people from Langzhong, Sichuan during the Qing Dynasty. At that time, Langzhong, Sichuan belonged to Baoning Prefecture, so Banxia koji was also called Baoning Banxia. You should be careful when purchasing it.

  Because Pinellia ternata contains homogentisic acid (black uric acid), it tastes spicy and bitter. In addition, because it contains ephedrine (ephedrine), it has an antitussive and phlegm-removing effect. In addition, because plants of the Araceae family contain calcium oxalate needle crystals, Therefore, it will irritate the mucous membranes of the mouth, lips and throat and cause discomfort. After high temperature treatment, the raw product will remove its vomiting-inducing ingredients. Therefore, if you want to use its vomiting-inducing effect, it must not be processed at high temperature. Because raw Pinellia ternata is poisonous, if you accidentally experience burning or numbing sensations in the mucous membranes of your mouth and throat, or stomach discomfort, nausea, or chest pressure, these may be symptoms of poisoning. You should seek medical attention immediately or use ginger to relieve the symptoms. The Chinese Pharmacopoeia published by Taiwan’s Department of Traditional Chinese Medicine regulates the standard content of sulfur dioxide and the content standards of heavy metals such as arsenic, cadmium, mercury, and lead to ensure the safety of people’s medication, so people can use it with peace of mind.
