Pharmacology
Through scientific investigation Cissus has been found to
exhibit various activities, including antioxidant,
antispasmodic, cytokine & blood sugar balancing,
gastroprotective, promoting comfort, gastrointestinal, liver
and bone health.
Cissus contains a number of bioactive compounds,
including flavonoids, ketosteroids, triterpenes, quercetin,
various polyphenols and stilbenes (such as pallidol,
resveratrol, quadrangularin A, piceatannol and
perthenocissin). Also present are vitamins and minerals,
such as Vitamin C & E, carotenoids, and calcium.
Several activities have been observed in preclinical studies,
which may be explained as mechanisms of action for its
role in promoting bone health. It has been observed to
stimulate bone growth and thickness, as well as osteoblast
proliferation, differentiation and mineralization.
Additionally, it has been found to decrease osteoclast
activity. In osteoplasts, it has been observed to increase
mRNA and protein expression of the Runt-related
transcription factor-2, a factor involved in bone
development. It is thought that the osteogenic activity of
Cissus is moderated by a MAPK-dependent mechanism.
Gastrointestinal effects have also been observed in
preclinical studies, confirming some of its traditional uses.
For example, antioxidant effects, such as glutathione, have
been observed which may be an underlying mechanism for
its gastroprotective effects. It has also been observed to
stimulate gastric cell proliferation and increase the
secretion of gastric mucus.
