This study investigated the pharmacological effects of Paris vietnamensis, finding it possesses anti-inflammatory and hemostatic properties. These findings support its use as a valuable alternative to traditional Paris Rhizoma, aiding resource conservation.
Area of Science:
- Pharmacology
- Traditional Chinese Medicine
- Ethnobotany
Background:
- Paris (Paridis Rhizoma) is a vital herb in Traditional Chinese Medicine, facing resource scarcity.
- Several related Paris species are utilized, necessitating comparative pharmacological evaluation.
- Ensuring sustainable sourcing and meeting market demand for Paris is crucial.
Purpose of the Study:
- To compare the pharmacological activities of Paris vietnamensis with pharmacopoeial Paridis Rhizoma.
- To evaluate the anti-inflammatory, hemostatic, and blood rheology effects of P. vietnamensis.
- To explore the potential of P. vietnamensis as a sustainable alternative for Paris medicinal resources.
Main Methods:
- Experimental comparison of P. vietnamensis and pharmacopoeial Paridis Rhizoma.
- Assessment of anti-inflammatory effects using carrageenan-induced rat paw edema.
- Evaluation of hemostatic effects by measuring bleeding and clotting times in rats.
- Analysis of blood rheology parameters in an acute blood stasis rat model.
- Measurement of capillary permeability in mice induced by acetic acid.
Main Results:
- P. vietnamensis, P. polyphylla var. yunnanensis, and P. polyphylla var. chinensis demonstrated significant anti-inflammatory and hemostatic effects.
- These species effectively reduced rat paw swelling, shortened bleeding and clotting times, and improved blood rheology.
- P. vietnamensis and P. polyphylla var. yunnanensis showed efficacy in inhibiting acetic acid-induced capillary permeability in mice.
Conclusions:
- Paris vietnamensis exhibits significant anti-inflammatory, hemostatic, and blood rheology-improving properties.
- These findings validate the medicinal use of P. vietnamensis and support its inclusion as a valuable resource.
- Expanding the use of P. vietnamensis can help conserve wild Paris resources and meet market demands.
