Cannabis has a potential for clinical use often obscured by unreliable and purely anecdotal reports. The most important natural cannabinoid is the psychoactive tetrahydrocannabinol (delta9-THC); others include cannabidiol (CBD) and cannabigerol (CBG). Not all the observed effects can be ascribed to THC, and the other constituents may also modulate its(More)
Exposure to the tiglian 12-O-tetradecanoylphorbol-13-acetate (TPA) represents one of the most efficient and widely used protocols for inducing Epstein-Barr virus (EBV)-infected cells from latent into lytic cycle. Since TPA is both a potent tumor promoter and a potent activator of the cellular protein kinase C (PKC), we sought to determine whether either of(More)
A brief history of the therapeutic uses and legal problems of cannabis as well as the component cannabinoids is given. This is followed by a discussion of drug development from Delta (1)-tetrahydrocannabinol and its synthetic analogues. The controversy of whether the pharmacological effects are of central or peripheral origin is included. Then, the(More)
Two extacts ofCannabis sativa herb, one being cannabinoid-free (ethanol) and the other containing the cannabinoids (petroleum), were shown to inhibit PBQ-induced writhing in mouse when given orally and also to antagonize tetradecanoyl-phorbol acetate (TPA) -induced erythema of mouse skin when applied topically. With the exception of cannabinol (CBN) and(More)
Methanol-preserved latices of E. poisonii and E. unispina were examined for irritant principles. Six esters of the parent diterpene 12-deoxyphorbol were identified by spectroscopic and chemical methods. Three were the aliphatic esters 12-deoxyphorbol-13-(2-methyl-butyrate), 12-deoxyphorbol-13-angelate and 12-deoxyphorbol-13-isobutyrate, and a further three(More)

A conceptual framework is presented to help the reader understand some controversies in the hypnosis literature and a means of understanding some important differences and disagreements in the field. It is this author's view that hypnotic behavior can be understood as a complex mix of four conceptual (and empirical) independent dimensions: expectations,(More)
Phorbol esters were isolated from the seeds of Chinese tallow (Sapium sebiferum L. Roxb.). These compounds were based on the tigliane nuclei, 4-deoxyphorbol, 12-deoxyphorbol and 4,20-dideoxy-5-hydroxyphorbol. The pro-inflammatory activity (ID50) of the pure compounds was between 0.042 and 2.6 nmoles per ear. Protein kinase C activation assays were carried(More)
