Cannabis sativa seed oil, also known as hemp seed oil, is a lightweight oil that's extracted from the seeds of the hemp plant (Cannabis sativa) through cold-pressing. It's distinct from CBD oil, as it contains minimal or no THC (the psychoactive compound) and typically little to no CBD. Instead, it's rich in omega-6 and omega-3 fatty acids and other nutrients, making it popular for both culinary and cosmetic uses.
