Anti-carcinogenic activity is also shown by monoterpene compounds in Mentha
piperita oil (Dorman et al. 2003, Romero-Jimenez et al. 2005). Zingiber officinalis
(ginger) rhizomes contain gingerols with pronounced anti-inflammatory activity
against various cancers (Katiyar et al. 1996, Kikuzaki and Nakatani 1993).
Gaidhani et al. (2013) evaluated Taxus baccata L and compound formulations
like Triphala ghrita, Khadirarista, Madhusnuhi rasayana, Maha triphaladya ghrita,
and Panchatikta guggulu ghrita indicated in ayurvedic texts for management of
cancer/tumour. Cedrus deodara (Roxb.) ex Lamb. and Berberis aristata (Roxb.) ex
DC. showed maximum anti-cancer activity (against 3 cell lines) as compared to
Withania somnifera Dunal. (against two cell lines) and Picrorhiza kurroa and Piper
longum L. (against one cell line).

Conclusions
The chapter gives a new perspective on cancer prevention and cure using biomolecules from plants/ayurvedic sources. Natural compounds tend to have an undeniable
role in cancer prevention and cure. Drug discovery from medicinal plants is time
consuming and cumbersome. Techniques such as nuclear magnetic resonance spectroscopy and mass spectroscopy could facilitate compound isolation from medicinal
plants. Though it is challenging, medicinal plants still remain a major source/reservoir of novel drug candidates for cancer. In the near future, plant-derived compounds could hold a major share in the array of cancer medicines available for
therapy.
