CBD is one of the newest and most important products in the Western World. The amount of people using CBD oil, paste or capsules has doubled in the last year. However, there is also much confusion about what it actually does, how to use it, herb-prescription drug interactions, and the difference between the different products? Complementary practitioners are not trained in the benefits or contraindications of cannabis when used medically. There is a paucity of knowledge, information and guidance about this new product, with a plethora of "internet help forums" springing up and many manufacturers of "CBD oil" products trying to get onto the bandwagon - often with products of dubious quality and vague ingredients. The book aims to fill that gap with an accessible guide that includes a history and overview of CBD and cannabis, what conditions they can help with, a detailed look at cannabinoids, THC, enodcannabinoids and the endocannabinoid system, the different types of cannabis, the phytochemistry of cannabis, other herbs to use with CBD and cannabis, legal issues, case histories and issues around clinical use.
