Sea-Ear Shell … Safety & Interactions
Shi Jue Ming · Concha Haliotidis
Use with caution. Practitioner review recommended before use.
Contraindications
- Spleen and Stomach deficiency cold without rising-Yang or eye-heat pattern
- Use of poorly cleaned or contaminated shell material
Cautions
- Like other calcium-rich shell medicinals, Shi Jue Ming can interfere with absorption of some medications if taken at the same time.
- Only properly cleaned medicinal shell should be used because marine shell materials can carry contamination if poorly sourced.
- The shell is heavy and typically needs appropriate decoction handling rather than casual powder use.
