The reported numbers of food allergies by people who consume hemp frequently have been rare but they do exist. Chemically, hemp is 100% organic and all-natural which makes it a great food with least or zero risks for the human body. But, since we cannot generalise genetics and biology to the core, hemp food can cause some mild allergic reactions in the body. These include irritation, swelling, puffiness of the eyes, skin rashes, running nose, sneezing, and conjunctivitis.
