This process requires the hemp to be soaked in ethanol for anything from a few hours to several days. Next, the product is filtered, leaving only the ethanol mixed with the CBD. As in the method above, the plant material is then heated to remove the ethanol and leave the extracted CBD ready for mixing with a base oil.
Ethanol extraction is widely considered as being safe as ethanol has antibacterial properties. Please do note that this method can give the final product a grass-like taste.
