SK3 Group Inc.'s announced a new product line Dharmanol Citrolene. Along with many studies on treating cancer with D-limonene, other studies have shown that the molecule attaches to the same receptor sites in humans as benzodiazepines such as Valium and Xanax. It is suggested that D-limonene stimulates these sites in the same manner that cannabis stimulates the Anandamide receptors in the human body.

Because the relaxing and depressive effects of Valium and Xanax are well known, it is thought that natural chemicals stimulating the same receptors will have similar actions, but with greatly reduced toxicity. D-Limonene is thought to be responsible for much of the relaxing effects of smoked cannabis. These effects are often absent in refined cannabinoid extracts which have many of the elements of the plant removed.

A substantial dose of D-limonene is present in Dharmanol Citrolene. When combined with the CBD, mixed cannabinoid carboxylates, and the steam-extracted terpene mixture that compromises the basic Dharmanol formula, D-limonene helps to provide much of the synergistic "whole plant" effect that many patients have found to be far superior to refined preparations where many of the essential elements of the plant are removed and discarded.
