Chitrakmool Plumbago Zeylanica safety, side effects, toxicity, review of plumbagin
In Ayurvedic medicine, chitrakmool has been mentioned as having pungent, astringent, diuretic, germicidal, and vesicant properties. Others mention chitrakmool to have benefit in terms of digestive, nervous and female reproductive system. Used in indigestion, gas, hemorrhoids, rheumatism, promotes sweating and small doses stimulate the central nervous system. See a list of Ayurvedic herbs. Chitrakmool is also a medicinal plant commonly used in Ethiopia for skin diseases.
As of April 2009 we could not find published human research with Chitrakmool herb.

Pancreatic cancer is one of the most resistant malignancies. Several studies
have indicated that plumbagin isolated from Plumbago zeylanica possesses
anticancer activity. However, its antitumor effects against pancreatic cancer
have not been explored. Methods: We investigated the effect of plumbagin on the
growth of human pancreatic carcinoma cells and its possible underlying
mechanisms. Results: Plumbagin inhibited the growth of Panc-1 and Bxpc-3 cells
in a dose-dependent and time-dependent manner. Liu's staining and transmission
electron microscopy demonstrated morphological changes resembling apoptosis in
Panc-1 cells treated with plumbagin. The degree of apoptosis was assessed by
measuring the proportions of sub-G(1), annexin V+/propidium iodide-, and
terminal- deoxynucleotidyl-transferase-mediated-nick-end labeling (TUNEL)+
cells, and a significant increment in apoptotic cells was observed. Exposure to
plumbagin caused the upregulation of Bax, a rapid decline in mitochondrial
transmembrane potential, apoptosis-inducing factor overexpression in cytosol,
and the cleavage of procaspase-9 and poly ADP-ribose polymerase. Activation of
caspase-3, but not caspase-8, was evidenced by fluorometric substrate assay.
Pretreatment with caspase inhibitors did not block plumbagin-induced apoptosis.
Alternatively, it is possible that plumbagin downregulated phosphoinositide
3-kinase activity through a negative feedback mechanism. In an orthotopic
pancreatic tumor model, plumbagin markedly inhibited the growth of Panc-1
xenografts without any significant effect on leukocyte counts or body weight.
Plumbagin may induce apoptosis in human pancreatic cancer cells primarily
through the mitochondria-related pathway followed by both caspase-dependent and
caspase-independent cascades. It indicates that plumbagin can be potentially
developed as a novel therapeutic agent against pancreatic cancer.
Chitrakmool safety, side effects,
toxicity
Genotoxicity of
plumbagin and its effects on catechol and NQNO-induced DNA damage in mouse
lymphoma cells.

Plumbagin, a naphtoquinone present in the roots of
plumbago
zeylanica has been reported to have many beneficial
effects such as antibacterial, antifungal, anticancer, antimutagenic and
antioxidant effects, but this compound has also been reported to have many side
effects. Given the wide use of P. zeylanica in traditional medicine and the
various potential therapeutic uses of plumbagin, the present study was carried
out to further elucidate the potential genotoxicity and antigenotoxicity of
plumbagin in mouse lymphoma L5178Y cells, using the comet assay. Without
affecting the cell viability, plumbagin itself was found to induce significant
DNA damage at low concentrations. When the cells were exposed to
non-DNA damaging concentrations of plumbagin, together with NQNO (known to
interact with DNA in many different ways) or catechol (known to induce oxidative
DNA damage), plumbagin was found to significantly reduce the catechol-induced
DNA damage, but to be without protective effect against the NQNO-induced damage.
The fact that non-DNA damaging concentrations of plumbagin diminished the DNA
damage induced by catechol, provides further support for the idea that plumbagin
may act as an antioxidative agent at low concentrations.
