Papa & Barkley's 1:1 CBD:THCa Releaf Tincture is a wonderful blend of cannabinoids for those who want the benefits of THC without the psychoactivity. THCa is the precursor to THC (THCa turns into THC when heated). Research has found that THCa has anti-inflammatory properties to help with conditions like lupus and arthritis, antidiabetic properties which can reduce the risk of developing early onset diabetes, neuroprotective properties to treat neurodegenerative diseases, and antiemetic properties to battle loss of appetite and nausea. 3.74 mg THCa/3.7 mg CBD per dose.
