Immature Bitter Orange Fruit … Safety & Interactions
Zhi Shi · Fructus Aurantii Immaturus
Use with caution. Practitioner review recommended before use.
Contraindications
- Pregnancy without qualified supervision
- Marked qi deficiency, prolapse, or digestive weakness without true stagnation
Cautions
- Because Zhi Shi is strongly descending and moving, it is easier to overuse than gentler citrus regulators such as Zhi Qiao or Chen Pi.
- Weight-loss or stimulant bitter-orange extracts can deliver far higher p-synephrine exposure than traditional decoction use.
- Medication review matters when concentrated bitter-orange products are used because transport and metabolism effects have been reported.
