5. Cautions and clinical notes

• Contraindications:

  • Cang Er Zi in this formula is toxic and should not be taken in excess or over a prolonged period. ProCare Herbs granules must be strictly processed and dosage controlled during preparation.
  • If any discomfort occurs during administration, use should be discontinued immediately.

6. Granule conversion and dose (based on a total raw herb weight of 30 grams)

• Calculation of raw herb weight in the original formula (based on a total of 30 g):
  • Cang Er Zi: 30g * 70.18% = 21.05g
  • Xin Yi: 30g * 14.04% = 4.21g
  • Jin Yin Hua: 30g * 5.26% = 1.58g
  • Ju Hua Ye: 30g * 5.26% = 1.58g
  • Qian Cao: 30g * 5.26% = 1.58g
  • Total weight: 30g
• Conversion to 5:1 granules:
  • 30 g raw herbs ÷ 5 = 6 g granules.
• Suggested dosage:
  • One dose per day, taken in 2 divided doses (morning and evening) dissolved in warm water, about 3 g per dose.
  • Or as directed by a physician. This formula is a specific formula for bi yuan; the duration of use must be determined by a physician according to the condition, and treatment should stop once the disease resolves — it should not be taken for a prolonged period.
