Can fresh Gynostemma be steeped in water for drinking?

Generally, fresh Gynostemma pentaphyllum is not recommended for direct consumption as tea. The detailed explanation is as follows:

Gynostemma pentaphyllum is a traditional Chinese herb with slightly cold properties that affects the spleen and lung meridians. It has functions including strengthening the spleen and boosting qi, resolving phlegm and relieving cough, clearing heat and detoxifying, and reducing lipid levels and turbidity. It can be used to treat conditions such as fatigue and poor appetite due to spleen and stomach qi deficiency, dry cough from lung deficiency, and sore throat. However, fresh Gynostemma contains gypenoside (red Gynostemma glycoside), making it unsuitable for direct infusion in water, as this may lead to poisoning.

It is recommended to use dried Gynostemma as a medicinal herb or to consume it only after standardized processing. Additionally, because Gynostemma is cooling in nature, individuals with cold constitution, gastrointestinal issues, and pregnant women should avoid its use. Those allergic to Gynostemma must refrain from using it entirely.

If fresh Gynostemma is required, it should only be used under the guidance of a physician to prevent improper use and potential adverse effects on health.
