Ginsenosides (e.g., Rg3, Rh2) Ginseng
-
Cancer Types mentioned: Hepatocellular carcinoma (HCC), lung cancer, and melanoma.
-
Food Occurrences: Found exclusively in Ginseng roots (Panax ginseng), which are used in specialty foods, teas, and supplements.
-
Summary of the Topic: Ginsenosides are steroid-like saponins that serve as the primary bioactive compounds in ginseng. Specific derivatives like Rg3 and Rh2 have been identified for their ability to induce apoptosis through mitochondrial pathways and inhibit tumor-induced angiogenesis.
-
They are particularly noted for their “tonic” effect, which helps improve the general health condition of cancer patients by balancing immunity and reducing fatigue during conventional treatment. Multi-omics studies have recently revealed how ginsenosides reshape transcriptional networks to reverse multidrug resistance and sensitize resistant cancer cells to drugs like cisplatin.

Remainder of Report & Sources:
-
Mechanisms: Upregulation of Bax/caspase-3, downregulation of Bcl-2, and inhibition of P-gp binding.
-
Combinations: Rh2 combines with betulinic acid to trigger the mitochondrial apoptosis pathway.

Primary Source: Cui et al., Chinese Medicine, 2025
-
-
Primary Food Sources: Panax Ginseng.
-
Molecular Targets: Primarily acts as an Anti-angiogenic agent by suppressing VEGF and bFGF. Rh2 specifically induces cell cycle arrest at the G1 phase by modulating cyclin-dependent kinases.
-
Bioavailability: Generally low; the rare “minor” ginsenosides (like Rg3) are more bioactive but harder to extract.

Cross-Links:
-
EGCG: Enhances the induction of apoptosis in gastrointestinal cancers.
-
Ursolic Acid: Some studies suggest Rh2 and UA work together to induce apoptosis in drug-resistant HeLa cells.
