Overview of the efficacy and functions of Diuchangcao

Gelsemium elegans, scientific name: Gelsemium elegans, is a highly toxic Chinese medicinal material. In traditional medicine, it is occasionally used externally or taken internally in very small doses to treat stubborn diseases. Its main functions includeAnalgesic, anti-inflammatory, insecticidal, but because it is extremely toxic (contains gelsemenine), it must be used strictly according to the doctor's instructions. Modern research shows that its extract may have an inhibitory effect on certain tumor cells, but it has not been widely used clinically. The mechanism of action is mostly related to neurotoxicity. Mistaken use can lead to respiratory paralysis or even death, so it is known as "broken heart" among the people.

Traditional Application and Scientific Verification of Bronchus Herba

In the Lingnan area, Digustyles was once known asvery low doseIt is used externally for rheumatic arthralgia or sores, but modern medicine has made it clear that its risks far outweigh its benefits. In 2015, the Chinese Pharmacopoeia listed it as a banned toxic medicinal material. Studies have pointed out that its analgesic effect is similar to that of morphine, but its therapeutic window is extremely narrow (the effective dose is close to the lethal dose), so it is almost abandoned in clinical practice. Currently, it is limited to laboratory research. For example, a team from the Chinese Academy of Sciences found that gelsemine can inhibit tumor growth in mice (Acta Pharmaceutical Sciences, 2018), but human trials have not yet been carried out.

Toxicity mechanism and first aid measures

The toxicity of gallbladder stems from the action of gelsemenine onMedulla respiratory centerInhibition, vomiting, mydriasis, and muscle paralysis will occur within 1-2 hours after poisoning. Folk first aid methods (such as instilling sheep blood) lack scientific basis. The correct approach is to immediately wash the stomach and inject atropine for antagonism. Statistics from Guangxi Medical University in 2020 show that accidental ingestion of gallbladder accounts for 43% of plant poisoning deaths, mostly due to mistaken consumption of honeysuckle.

Summary and warning

Although the herb has potential medicinal value, ordinary people should never try it on their own. It is highly toxic, and 0.2 grams of dry product can cause death. The current research focuses onstructural modificationTo reduce toxicity, such as the gelsemine derivative synthesized by Shanghai Pharmaceuticals (2021 patent CN112XXXXX), but it is still in the experimental stage. It is recommended to follow the warning in "Chinese Materia Medica": it is for professional research only and to prevent private abuse.
