Eczema

A comparative study into the topical anti-inflammatory activity of cannabinoids (on croton oil-inflamed skin in mice) showed that Δ8THC, Δ9THC and THCV are about half as effective in reducing inflammation as Indometacin (a commonly used Non-steroid anti-inflammatory drug), but approximately 5 times more effective than CBCV and CBDCBC and CBDV had no appreciable anti-inflammatory activity (Tubaro et al., 2010).

epilepsy

In a mouse model of epilepsy (Maximal Electro Shock), the following cannabinoids were found to be anti-convulsive (ED50)(referenced within: Devinsky et al., 2014): CBD 120 mg/kg Δ9THC 100 mg/kg 11-OH-Δ9THC 14 mg/kg 8β-OH-Δ9THC 100 mg/kg Δ9THCA 200-400 mg/kg Δ8THC 80 mg/kg CBN 230 mg/kg Δ9α/β-OH-hexahydro-CBN 100 mg/kg Apart from that the doses reported above are incredibly high, it does provide a proof of principle that many cannabinoids exert anti-convulsive effects.
