What happens if Heishunpian (Black顺片) is boiled for a short period of time?

Generally, if the processing time of Black Prepared Slices (Hei Shun Pian) is too short, it may result in insufficient medicinal effects, incomplete release of active ingredients, astringent taste, poor absorption, and gastrointestinal irritation. If any abnormalities occur, it is recommended to seek medical advice promptly. Detailed explanations are as follows:

1. Insufficient medicinal effects: If the processing time of Black Prepared Slices is too short, the active ingredients may not fully dissolve, thus reducing the medicinal effects and impacting treatment outcomes.

2. Incomplete release of components: The nutritional and medicinal components in Black Prepared Slices require sufficient time to be fully released. Inadequate processing time may prevent some active substances from being fully utilized.

3. Astringent taste: Insufficient processing time may result in incomplete transformation of tannins and other components, leading to an astringent taste and negatively affecting the sensory experience.

4. Poor absorption: If the ingredients in the herbal materials are not sufficiently dissolved, the human body may struggle to absorb them, thereby reducing the actual efficacy of nourishment or regulation.

5. Potential gastrointestinal irritation: Some incompletely decomposed components in Black Prepared Slices may irritate the gastrointestinal tract, causing bloating or discomfort, especially in individuals with sensitive digestive systems.

It is recommended to strictly follow the guidance of a TCM practitioner. Black Prepared Slices should be decocted together with other herbs for at least 1.5 to 2 hours, ensuring prior and prolonged decoction to reduce toxicity.
