Clinical Effects of the Extract of the Seeds of the Indian Celery-Apium Graveolens-In Horses Affected by Chronic Osteoarthritis.

The extract of the seeds from Indian celery, Apium greaveolens (CSE), tested in experimental animals (rodents), and in humans aected by chronic osteoarthritic diseases, exhibits anti-inflammatory eects that can be compared, to some degree, to those of non-steroid anti-inflammatory drugs (NSAID). In view of a potential use of CSE in the equine species, it was tested on horses aected by chronic articular pathologies. The trial was performed on 20 horses divided into three dierent groups, orally treated with 0 (controls), 7.0 or 30 g of CSE BID. Basic orthopedic examinations were conducted, vital signs were observed, and blood samples collected. Improvement was observed at the highest dosage tested (30 g of CSE BID), as reflected in the score values of three clinical parameters, (i) amplitude and (ii) sensitivity to passive flexion and (iii) flexion test. Since the improvement of these parameters can be correlated with a lower perception of the pain, the present data suggest that the CSE treatment can have an analgesic eect in horses aected by chronic osteoarthritic diseases.
