Holy Grail is an even 50/50 hybrid of sativa and indica. The buds are dense and sometimes feature a bluish tinge to it.  The effects are more similar to a smooth relaxed type of buzz, with you feeling happy, upbeat and ready to be creative after smoking it. Due to its potency, it is very commonly used as a pain reliever in medicine, but is also used to treat insomnia, stress and nausea.
