Medical Marijuana, now legal in over half the USA comes from a medicinal-grade cannabis plant free of chemical residues from toxic pesticides and fertilizers. Its therapeutic and healing properties result from cannabidiol (CBD) and tetrahydrocannabinol (THC) as well as medical terpenes and flavonoids interacting with cannabinoid receptors in the brain, lungs, liver, kidneys, and immune system. CBD works as an excellent painkiller, treats anxiety issues, enhances sexual libido, stimulates appetite, and helps alleviate nausea. Common ailments treated with medical marijuana include mood disorders, degenerative neurological disorders, multiple sclerosis, Parkinson’s disease, PTSD, seizures, and some cancer treatment. Medical marijuana can be used in pet treatments for arthritis, pain and inflammation, and bad behavior. Medical marijuana can be administered to patients using one of the following methods: Inhalation, smoking, vaporization, under the tongue, oral mucosal, oral ingestion, rectally, or topical application.
