All Gron people products are THC free made with CBD Isolate. Gron Pet products are made from Full Spectrum CBD Oil. As far as extraction goes their process for people based products is as follows - First, they start the extraction process using ethanol, which gives us Rick Simpson Oil (RSO). They always use ethanol because we want it to be consumable. Second, we use a triple distillation process on the RSO that removes the terpenes, waxes, and plant material, giving the oil a honey-like look and texture. Third, the THC is taken out, and CBD is isolated through heat and light using a process called chromatography.
