Is it really good to drink Pangdahai regularly?

Many people drink Sterculia lychnophora tea to help relieve sore throat problems, but it should be noted that Sterculia lychnophora should never be consumed for a long time, because it actually contains certain toxicity, and it is not suitable for people with weak spleen and stomach constitution.

1. Traditional Chinese medicine theory: Many people are not suitable for using Pandanus lychnophora.

Plantago ovata is the dried mature seeds of the deciduous tree Plantago ovata of the Sterculiaceae family. This medicine was first recorded in "Supplement to Compendium of Materia Medica" and is commonly known as "Dafa" because when it comes into contact with boiling water, its skin cracks and swells, almost filling the entire cup.

Traditional Chinese medicine believes that Plantago ovata is cold in nature and sweet in taste, and has two major functions. One is to clear the lung qi, and can be used for acute pharyngitis and tonsillitis caused by wind-heat invading the lungs, such as feeling fever, sore throat, dry mouth, and dry cough during a cold; the other is to clear the intestines and promote bowel movements, and can be used for constipation caused by getting angry.

2. The following situations are not suitable for using Sterculia lychnophora:

One is a weak spleen and stomach constitution, which is manifested by decreased appetite, cold pain in the abdomen, preference for warmth and pressure, and loose stools. Taking Sterculia lychnophora at this time can easily cause diarrhea and damage vitality;

The second is cough and sore throat caused by cold, which is manifested by aversion to cold, physical weakness, and coughing up white sticky phlegm;

The third is cough caused by lung yin deficiency, which is also manifested as dry cough without sputum and hoarseness, but this situation is mostly a chronic respiratory disease.

3. Pharmacological research has also proved that Sterculia lychnophora is not suitable for long-term use.

Phytochemical research has found that the outer layer of Plantago ovata seeds contains astragalin, and the peel contains galactose, pentose and other ingredients. Other studies have shown that Sterculia lychnophora can promote small intestinal motility and produce a mild laxative effect. People with poor gastrointestinal function should not take it for a long time. The drug also has a blood pressure lowering effect. Therefore, people with normal or low blood pressure may be at risk of low blood pressure if they take it for a long time. In addition, the water-extracted extracts of Sterculia lychnophora peel, soft shell, and kernel have certain analgesic effects, with the kernel having the strongest effect. The analgesic principle is currently unknown, but it is certain that if the analgesic effect is caused by inhibition of the central nervous system, long-term use of Sterculia lychnophora may also be potentially dangerous.
