For breast cancer
Vitamin A (fenretinide)200 mg/day significantly reduces the recurrence of local breast cancer in premenopausal women[4]
Vitamin ELeads to malabsorption or maldigestion in cancer patients; balanced and healthy diet[5, 6]
Isoflavone To reduce risk of breast cancer[10]
Isoflavones genistein and daidzeinTo confer weak estrogenic effects[11]
Alkaloids Inhibition of cancer cell growth[13, 14]
CoumarinsInhibition of cancer cell growth[15, 16]
Flavonoids and polyphenolsAntiproliferation [17, 18]
TerpenoidsMCF-7 cell apoptosis[19]
QuinoneTo induce G2-M arrest and autophagy by inhibiting the AKT/mammalian target of rapamycin pathway in breast cancer cells[20]
ArtemisunateDecrease the proliferation of human breast cancer cells from expressing a high ERα : ERβ ratio[21]

For prostate cancer
Vitamins A-D and retinoidMaintain homeostasis and prevent various metabolic disorders[23]
Vitamin EReduce the risk of lethal or advanced prostate cancer relative to nonusers[30]
Epigallocatechin-3-gallate (EGCG)Arrest LNCaP and DU145 prostate cancer cells at the G0-G1 phase of the cell cycle[34]
Inhibit metalloproteinase in vitro [35]
Soy isoflavonesInhibit 5α-reductase activity[37]
Chemopreventive activities[22]
Scutellaria baicalensis (baicalin)Inhibit enzymatic synthesis of eicosanoids[38]
BaicaleinImpair the proliferation of androgen-independent PC-3 and DU145 prostate cancer cells in culture[39]
Induces cell-cycle arrest at the G0-G1 phase[39]
Induces apoptosis of prostate cancer cells at concentrations achievable in humans[40]
Suppresses the expression of specific androgen receptor in prostate cancer[40]
LycopenesDecreases prostate cancer risk [41]
Diminishes oxidative damage in lymphocytes [42]
Significantly decreases levels of PSA and less oxidative damage[42]
PC-SPESDecreases serum testosterone concentrations ( ); decreases serum concentrations of prostate-specific antigen[43]
Antitumor efficacy against cancer cell lines[44]
Wedelia chinensis (Asteraceae)Inhibits the androgen receptor (AR) signaling pathway[47]

For lung cancer
Platycodon grandiflorum (Campanulaceae)Anticancer effect in lung cancer patients[4951]
Morus alba (Moraceae)Anticancer effect in lung cancer patients
Prunus armeniaca (Rosaceae)Anticancer effect in lung cancer patients

For liver fibrosis and cancer
Inchin-ko-to (TJ-135)Preventive effect on liver fibrosis[53]
Yi Guan Jian (YGJ)[53]
Yi Guan Jian (YGJ)[54]
Fufang-Liu-Yue-Qing [55]
Danggui Buxue Tang (DBT)[56]
Salvianolic acid B
Curcumin Suppressive effect on hepatic fibrogenesis and carcinogenesis [57]
Oxymatrine
Compound 861Suppressive effect on hepatic fibrogenesis [58, 59]
Sho saiko-to (TJ-9)Reduces/limits the progression of hepatocellular carcinoma[60]

For pancreatic cancer
GDC-0449, IPI-926, XL-139 and PF-04449913SMO antagonists; deregulation of sonic hedgehog homology (SHH)[61]
CyclopamineInhibit SHH signaling by directly binding to the 7-helix bundle of the SMO protein; arrest the growth of pancreatic tumors[62]
Weakens the recruitment of BMPCs into cancer cells and reduces the formation of tumor vasculature[63]
The cancerous vascular system becomes unstable after treatment with cyclopamine due to the expression of angiopoietin-1[63]
