RSO=Rick Simpson Oil named after its inventor who was of the original stoners who cultivated Humbolt County, Ca into a cannabis capital in the 1960-1970’s. An entire plant is flash frozen to create RSO and you’ll find detailed info here. https://www.wikileaf.com/thestash/rick-simpson-oil/
I buy my own clear capsules on Amazon and buy the RSO higher in CBD than typically seen in vapes. I fill the capsules once a month or you can buy them prefilled at dispensaries. It’s an additional tool to help me stay away from oxycodone, permits me to tolerate my pain causing activities like cooking. I don’t get buzzed any longer which is ok with me.
