Yes, CBD tincture does work! CBD tincture works in conjunction with the endocannabinoid system. Because CBD is a cannabinoid, it helps supplement the bodys natural cannabinoids, strengthening the endocannabinoid system. In other words, the endocannabinoid system is a vast system of cannabinoid receptors. Furthermore, the body itself produces its own natural cannabinoids. CBD oil or cannabidiol, in general, is known as a phytocannabinoid (plant-based cannabinoid) that can help to supplement the endocannabinoid system (ECS).
I have also used it on my dogs. From dementia and relaxing my 16 year old dog at night to sleep without harsh tranquilizers before she died. To now, my new dog had dental problems, rubbing it on her gums helped her pain until i could get her to the vet to have her teeth pulled. I also give her some to calm her before a storm.
It is safe and you can decide on the dosage.
I try to buy a few botles when it is on sale to always have it in the house.
