What is Medicinal Plants in Cancer Therapy?

Medicinal Plants in Cancer Therapy screens plant extracts and phytochemicals for cytotoxicity, apoptosis induction, and angiogenesis inhibition against cancer cell lines to identify novel anticancer agents.

Researchers evaluate plant-derived compounds like eugenol from clove and flavonoids for anticancer potential using bioassays on cell lines. Studies highlight green synthesis of nanoparticles from plants such as Syzygium alternifolium for synergistic anticancer effects (Yugandhar et al., 2017, 218 citations). Over 10 high-citation papers from 2010-2021 document these activities, with eugenol review garnering 535 citations (Kamatou et al., 2012).

Key Challenges

Why It Matters

Plant-derived agents like paclitaxel address chemotherapy resistance in cancers such as ovarian and breast tumors. Eugenol from Syzygium aromaticum shows cytotoxicity against cancer cells (Kamatou et al., 2012). Green-synthesized silver nanoparticles from plant extracts enable targeted cancer theranostics, reducing toxicity (Ovais et al., 2016). Copper oxide nanoparticles from Syzygium alternifolium exhibit synergistic anticancer activity (Yugandhar et al., 2017). Flavonoids from plants offer therapeutics for cancer via antioxidant mechanisms (Mutha et al., 2021).

Key Research Challenges

Cytotoxicity Specificity

Distinguishing cancer cell killing from normal cell toxicity remains difficult in plant extract screening. Bioassays often show broad cytotoxicity without selectivity data (Khan et al., 2012). Advanced models like 3D spheroids are needed for better prediction.

Bioavailability Limitations

Phytochemicals like eugenol face poor absorption and rapid metabolism, limiting clinical efficacy (Kamatou et al., 2012). Nanoparticle encapsulation aims to improve delivery but requires optimization (Ovais et al., 2016).

Clinical Translation Gaps

Moving from in vitro anticancer activity to preclinical trials lacks standardized protocols. Few plant compounds advance beyond cell line studies due to reproducibility issues (Yugandhar et al., 2017).
