Holy Grail OG is an indica dominant strain with a 60:40 indica/sativa ratio. Its potency is unmatched with an astounding 24-29% THC content. What is really interesting about the strain is that it is the first of its kind to achieve a perfect score in its category. The strain is also popularly referred to as Holy Grail Kush and is a cross between Kosher Kush and the OG #18 and has a complex flavor that is unique at the same time. It does taste like coffee with lime and hash undertones. But there is nothing different about its aroma, as it smells just like it tastes. The buds, however, are dense and large with blueish hues that make it stand apart from the rest of the crowd. Considering its THC content and with as much as 4% CBD levels, the strain proves to be effective due to its various medical applications. The strain offers numerous effects in body and mind that can be uplifting and calming at the same time. Holy Grail OG is renowned for calming anxiety and stress. But that is not all, as it just as effective for patients suffering from pains and aches, nausea and a lack of appetite.
