Assuming the medicine and not the drug store, is Snake Bone. I found this reference from a search.

"The flexibility of snakes has suggested that they might be helpful in the treatment of stiffness, for example, arthritis. Two types of snakes, agkistrodon and zaocys, are currently used in several traditional and patent prescriptions for arthritis, and they are sometimes soaked in alcohol to make an extract for stiff joints. The speed with which some snakes move indicated to traditional observers that, as medicines, their substance can move quickly around the body."
