Antiarthritic activity of a standardized, multiherbal, Ayurvedic formulation containing Boswellia serrata: in vitro studies on knee cartilage from osteoarthritis patients.

A validated in vitro model of cartilage damage and published data were used showing that this model measures the chondroprotective and antiinflammatory effects of different antiarthritic drugs. In this report, this model was used to evaluate the effects of a new antiarthritic Ayurvedic formulation containing Zingiber officinale root, Tinospora cordifolia stem, Phyllanthus emblica fruit and oleoresin of Boswellia serrata. Glucosamine sulphate was used as a positive control in the study.

Chondroprotective Potential of Fruit Extracts of Phyllanthus emblica in Osteoarthritis.

There is a need for effective nutraceuticals for osteoarthritis care. The fruit of Phyllanthus emblica is used as a powerful rejuvenator in Ayurvedic medicine. This study measured the chondroprotective potential of P.

The relationship between chondroprotective and antiinflammatory effects of Withania somnifera root and glucosamine sulphate on human osteoarthritic cartilage in vitro.

Using a validated explant model of in vitro cartilage damage, the effects of aqueous extracts of Withania somnifera (Ashwagandha) root and glucosamine sulphate (GlcS) were tested on the levels of nitric oxide (NO) and glycosaminoglycans (GAGs) secreted by knee cartilage from chronic osteoarthritis (OA) patients. W. somnifera extracts significantly decreased NO release by explants from one subset of patients (antiinflammatory response) and significantly increased levels of NO and GAGs released by explants from the second subset ('non-responders').

Hyaluronidase and collagenase inhibitory activities of the herbal formulation Triphala guggulu.

Myrrh (guggulu) oleoresin from the Commiphora mukul tree is an important component of antiarthritic drugs in Ayurvedic medicine. Clinical data suggest that elevated levels of hyaluronidase and collagenase type 2 enzymes contribute significantly to cartilage degradation. Triphala guggulu (TG) is a guggulu-based formulation used for the treatment of arthritis.

Chondroprotective potential of root extracts of Withania somnifera in osteoarthritis.

This is the first report describing two novel chondroprotective activities of aqueous extracts of Withania somnifera root powder.First,these extracts had a statistically significant,short-term chondroprotective effect on damaged human osteoarthritic cartilage matrix in 50% of the patients tested. Second,these extracts caused a significant and reproducible inhibition of the gelatinase activity of collagenase type 2 enzyme in vitro.

Differential growth inhibitory effects of W. somnifera root and E. officinalis fruits on CHO cells.

The Chinese Hamster ovary (CHO) cell line is widely used for measuring drug cytotoxicity and resistance. Therefore, the effects of two major Ayurvedic drugs (W. somnifera root and E.
