Hypothesis
The study aims to validate the traditional uses of Valeriana hardwickii as an antispasmodic and antidiarrheal agent.
Conclusion
The extract of Valeriana hardwickii exhibits spasmolytic and antidiarrheal activities, likely through calcium channel blockade.
Supporting Evidence
- Vh.Cr caused concentration-dependent relaxation of spontaneous contractions in isolated rabbit jejunum.
- Vh.Cr exhibited dose-dependent protection against castor oil-induced diarrhea in mice.
- Loperamide, a standard antidiarrheal drug, similarly prevented diarrhea.
Takeaway
This study shows that a plant called Valeriana hardwickii can help with stomach cramps and diarrhea by blocking certain channels in the body.
Methodology
The study involved testing the crude extract of Valeriana hardwickii on isolated rabbit jejunum and in mice with castor oil-induced diarrhea.
Participant Demographics
Balb-C mice and rabbits of local breed were used in the study.
