Cannabidiol (CBD), one of the active constituents of the cannabis plant, has profound healing and balancing effects on all mammals. Pet owners have used it for a broad spectrum of medical and behavioral issues — cancer pain, arthritis, muscle spasms, seizures, neurological and digestive disorders, anxieties, obsessions, past traumas, withdrawal, mood, and memory. During recovery from illness or surgery, CBD can stimulate the appetite and speed healing. At the end of life, it can ease the pain and fear your pet may be experiencing. CBD does all this by stimulating the endocannabinoid system.
