I found this while researching any negative side effects of Cissus. I'm thinking of adding it in my regimine for joint pain and was initially concerned that it was a carcinogen. I'm somewhat less worried now that I see the same studies say ginger and garlic are mutagenic. Anyone have an explanation for this?
Note the conflicting results on garlic and ginger:
"Spices like pepper, pippali, ginger and mustard increased the number of revertants indicating their mutagenic potential"

"garlic, palm oil, arrack, onion and pyrolysed portions of bread toast, chicory powder were weakly mutagenic, while tamarind and turmeric were not" ...
"Cissus quadrangularis was mutagenic"
