Pretty decent. I would recommend for PTSD symptoms.
Purple Head Knocker, also known as "Head Knocker" to many members of the cannabis community, is an indica dominant hybrid (80% indica/20% sativa) strain that is a potent cross between the insanely popular Durban Poison X Trainwreck strains. This dank bud boasts a THC level ranging from 20-25% on average and a combination of indica and sativa effects. Purple Head Knocker has a lemony pine aroma with a hint of sweet earth and a crisp taste of lemony pine with a sweet grape aftertaste upon exhale. Purple Head Knocker has compact dense round nugs that are light minty green with amber undertones, and are covered in rich purple curly leaves and fiery orange hairs. These nugs are caked in a thick layer of crystal white trichomes and a fine layer of resin. Users describe the Purple Head Knocker high as one that will completely leave your head spinning. You'll feel intensely energized and uplifted with a cerebral head buzz that starts in your temples and neck and works its way throughout your body into a deep warming body buzz. This will leave you sedated and couch-locked, almost in a stupor-like state. Due to these effects, this strain is ideal for treating chronic pain and stress as well as anxiety disorders.
