Do you know the effects and functions of Pinellia ternata?

Pinellia is a very good Chinese medicinal material. People often use it as food in daily life. Pinellia is a medicinal plant of the Araceae family and is mainly distributed in Northeast and North my country. It has significant effects on relieving cough and reducing phlegm, inhibiting glandular secretion, relieving emetics and inducing vomiting, anti-fertility and inhibiting trypsin. Many people also like to eat Pinellia ternata, so it is necessary to understand its specific effects.

1. The efficacy of Pinellia

Drying dampness and resolving phlegm, relieving adverse effects and stopping vomiting, eliminating lumps and dispersing nodules. It is used for cough and asthma due to excessive phlegm, dizziness and palpitations caused by phlegm and fluid, dizziness caused by wind and phlegm, headache caused by phlegm, vomiting and nausea, insomnia, goiter and phlegm nodules, carbuncle and swelling, chest and abdominal distension, and plum pit syndrome; it can be used externally in raw form to treat carbuncle and phlegm nodules. Ginger and Pinellia are often used to relieve nausea and stop vomiting.

2. The role of Pinellia

1. Antitussive effect

Decoctions of raw pinellia, ginger pinellia, ginger-soaked pinellia and alum pinellia, 0.6-1g/kgig or iv, have a significant antitussive effect on cough caused by iodine injection into the chest cavity of cats or electrical stimulation of the superior laryngeal nerve, and the effect can last for more than 5 hours.

2. Expectorant effect

Intraperitoneal injection of Pinellia ternata decoction in rats can significantly inhibit the effect of rutinine on saliva secretion. Mice were gavaged with ethanol extracts of raw pinellia and clear pinellia. The phenol red method showed that the ethanol extract of clear pinellia had a certain expectorant effect, while no obvious effect was observed for raw pinellia. Research by Zou Jilong and others shows that the longer the Pinellia is stored, the stronger its expectorant effect is.

3. Inhibit glandular secretion

The ip administration of Pinellia preparation has a significant inhibitory effect on the saliva secretion caused by piloscarpine. There are also reports that when the decoction is administered po, ​​the saliva secretion first increases and then decreases.

4. Antiemetic and emetic effects

Various preparations of Pinellia that are heated or prepared with alum and ginger juice have a certain antiemetic effect on vomiting caused by dehydrated morphine, digitalis, and copper sulfate. The above three emetics have different mechanisms of action, but Pinellia ternata can all show antiemetic effects. It is speculated that its antiemetic mechanism is the inhibition of the vomiting center.

5. Anti-fertility effect

Pinellia protein has a strong anti-rabbit blastocyst implantation effect. When 500ug is injected into the uterus, the anti-implantation rate reaches 100%. The endometrium acted upon by Pinellia protein can prevent the transplanted normal blastocyst from implanting. When blastocysts incubated with Pinellia ternata protein in uterus were transplanted into synchronized pseudopregnant uterus, the implantation rate decreased with the extension of incubation time.
