Sun Soup, selected vegetables, SV
Top
Clinical Summary
Proprietary product that contains water, soybean, shiitake mushroom, mung bean, red date, scallion, garlic, lentil bean, leek, hawthorn fruit, onion, American ginseng, angelica root, licorice, dandelion root, senegal root, ginger, olive, sesame seed, and parsley (1). Sun Soup was developed by a biochemist, Alexander Sun. Patients use this supplement in conjunction with conventional therapies to prevent and treat cancer, HIV/AIDS, promote weight gain, and as an immunostimulant.
Sun Soup exhibits antitumor activity in mouse models (2). Data from small open-label phase I/II studies of SV administered concurrently with conventional therapies for stage III and IV non-small cell lung cancer suggest improvements in survival, Karnofsky Performance Scale Score, and objective tumor regression (1). Larger randomized studies are needed to confirm these findings.
Side effects such as bloatedness and fullness after ingestion have been reported (1).

Mechanism of Action
The inventor suggests that the “modest” individual antitumor activities of chemicals in certain ingredients act synergistically (1). Quantitative analysis of freeze-dried powder (DSV) reveals approximately 63 mg inositol hexaphosphate (IP6), 2.6 mg genistein, 4.4 mg daidzein, and 15.5 mg coumestrol per serving (2). In vitro and animal studies performed with IP6 suggest it slows the initiation and/or promotion, inhibits proliferation by chelation of metalloproteins, causes G0/G1 arrest, and induces differentiation of various cancer cell lines. In vitro, genistein inhibits angiogenesis, induces DNA damage in cancer cell lines, and, with daidzein and coumestrol, inhibits the growth of human prostate cancer cell lines (3). Genistein and coumestrol have been shown to induce NADPH:quinone reductase (QR), a detoxifying phase II enzyme, in colonic cells, leading to possible antitumor effects (4). Shiitake mushrooms contain lentinan, a polysaccharide, which may act as an immunomodulator and enhance production of IL-1, TNF, LAK activity, cytotoxic T lymphocytes, and cytotoxic peritoneal exudate cells. A mouse tumor model showed that mice fed shiitake extract, mung bean extract, or both exhibited tumor inhibition of 60%, 53%, and 82%, respectively, as compared to the control group after 22 days.
