The name of this increasingly popular medical choice refers not to the potency of its high but to the power of its symptom relief. Purple Sour Tsunami has high THC levels, which makes it one of the most seizure-friendly medications on the market. That makes this a good choice for some children with severe epilepsy, as well as other patients whose conditions respond to CBD. A cross of Sour Diesel and NYC Diesel, this strain is a sativa-dominant hybrid with an unknown ratio of sativa to indica. This strain should be used to treat chronic pain, seizures, insomnia, and stress. It can also helps spur appetite in patients who need to eat more.
