Pharmakas® AKS Paste contains bitter substances and so effectively protects horses against the ingestion of foreign bodies, thus preventing serious injuries or illnesses (e.g. colic). In addition, AKS provides support in combating crib-biting (cribbing or windsucking). The bitter substance used does not present a health risk to humans and horses and, yet at the same time, is effective in preventing unwanted chewing. It has a long-lasting effect. Repeated application increases effectiveness.
