Author Information
Author(s): Ko Nishimura, Toshihiko Osawa, Kenji Watanabe
Primary Institution: Keio University
Hypothesis
The study aims to evaluate the oxygen radical absorbance capacity (ORAC) of various Kampo medicine formulas.
Conclusion
The ORAC values of Kampo medicine formulas vary widely, indicating their potential antioxidant capacity.
Supporting Evidence
- The ORAC value of Kampo medicine ranged from 4.65 to 5913 units per day.
- Kampo formulas containing Rhei Rhizoma showed high ORAC values.
- Formulas with anti-inflammatory herbs also demonstrated significant antioxidant capacity.
- The addition of different herbs can change the ORAC value of a Kampo formula.
Takeaway
This study looked at how well different Kampo medicines can fight bad stuff in our bodies, and found that some are really good at it!
Methodology
The study measured the ORAC values of 141 Kampo extract formulas, one herbal powder formula, and one ointment formula using a fluorescence-based method.
Limitations
The study did not evaluate the in vivo antioxidant effects of Kampo medicine and noted discrepancies between in vitro and in vivo results.
