Selected Vegetables/Sun's Soup
- "Selected Vegetables" and "Sun's Soup " are different mixtures of vegetables and herbs that are being studied as treatments for people with cancer (see Question 1).
- Dried and frozen forms of Selected Vegetables are sold in the United States as dietary supplements (see Question 1).
- The vegetables and herbs in Selected Vegetables/Sun's Soup may contain substances that block the growth of cancer cells and/or help the body's immune system kill cancer cells (see Question 2).
- Researchers reported that the growth of tumors was slower in the mice that were fed ingredients in Selected Vegetables/Sun's Soup, compared to the mice that ate standard food (see Question 5).
- Researchers reported that some cancer patients lived longer and had better quality of life when they received Selected Vegetables/Sun's Soup along with other treatments. Randomized controlled trials, enrolling larger numbers of people, are needed to confirm the results (see Question 6).
- No mixture of Selected Vegetables/Sun's Soup has been approved by the U. S. Food and Drug Administration for the treatment of cancer or any other medical condition (see Question 8).
Questions and Answers About Selected Vegetables / Sun's Soup
"Selected Vegetables" and "Sun's Soup " are names given to several different mixtures of vegetables and herbs that are being studied as treatments for cancer and other medical conditions, including acquired immunodeficiency syndrome (AIDS). The following versions have been used:
- Shiitake mushroom.
- Mung beans.
- Hedyotis diffusa.
- Scutellaria barbata (barbat skullcap).
This mixture is not sold in the United States.
Freeze-dried Selected Vegetables (DSV), a freeze-dried mixture of vegetables and herbs sold in the United States as a dietary supplement. DSV is reported to contain the following ingredients:
- Shiitake mushroom.
- Mung bean.
- Red date.
- Hawthorn fruit.
- Angelica root.
- Dandelion root.
- Senega root.
- Sesame seed.
- Frozen Selected Vegetables (FSV), a frozen mixture of fresh vegetables and herbs, sold in the United States as a dietary supplement. It contains the same vegetables and herbs as in DSV.
The vegetable and herb mixture now called Selected Vegetables/Sun's Soup was developed to treat cancer.
- In the mid-1980's, the developer created the mixture to treat a relative who was diagnosed with stage IV non-small cell lung cancer and not helped by standard treatment. The mixture contained shiitake mushroom, mung bean, and the herbs Hedyotis diffusa and barbat skullcap. The developer believed these ingredients contain substances that may block the growth of cancer cells and/or help the body's immune system attack cancer cells. The relative was reported to be alive and free of cancer more than 13 years later. Three more patients with advanced cancer were treated with a combination of shiitake mushroom and mung bean. These patients were also reported to benefit from the treatment.
- In 1992, the developer applied for a patent for Selected Vegetables/Sun's Soup as an herbal treatment of cancer. The developer reported on animal studies done in mice (see Question 5). The developer then began doing clinical trials (see Question 6) to test Selected Vegetables/Sun's Soup in cancer patients.
- In 1995, the developer was awarded a patent for Selected Vegetables/Sun's Soup.
Many of the vegetables and herbs in Selected Vegetables/Sun's Soup were chosen because previous research and traditional Chinese medicine suggest they contain anticancer phytochemicals (substances found in plants that may have effects on the body). These include substances such as protease inhibitors, plant sterols, and isoflavones. These ingredients may block the growth of cancer cells and/or improve the way the body's immune system attacks cancer cells.What is the theory behind the claim that Selected Vegetables/Sun's Soup is useful in treating cancer?
The theory is that certain ingredients in Selected Vegetables/Sun's Soup may contain phytochemicals that have significant anticancer effects in humans. One of these ingredients is shiitake mushroom. Lentinan, which is taken from shiitake mushroom, has been used in Japan to treat stomach and colon cancer after surgery. Treatment with lentinan is reported to help patients with stomach cancer live longer and have a better quality of life. Lentinan may not be easily absorbed by the body from food, so it is usually given by injection. Other substances in shiitake mushroom that are more easily used by the body from food have shown anticancer activity in animal tests.How is Selected Vegetables/Sun's Soup administered?
Selected Vegetables/Sun's Soup is eaten as part of the diet. Daily doses of either 1 ounce of the DSV (mixed with water or other soup) or 10 ounces of the FSV were used in clinical trials.Have any preclinical (laboratory or animal) studies been conducted using Selected Vegetables/Sun's Soup?
Few preclinical studies have been done with Selected Vegetables/Sun's Soup. Research in a laboratory or using animals is done to find out if a drug, procedure, or treatment is likely to be useful in humans. Preclinical studies are done before clinical trials (in humans) are begun.
A small number of mice were injected with tumor cells and fed either standard food or food mixed with one or more ingredients from Selected Vegetables/Sun's Soup. The researchers reported that the growth of tumors was slower in the mice that were fed the Selected Vegetables/Sun's Soup ingredients, compared to the mice that ate standard food. The tumor growth was slowest when the mice were fed both mung bean and shiitake mushroom.Have any clinical trials (research studies with people) of Selected Vegetables/Sun's Soup been conducted?
Clinical trials using Selected Vegetables/Sun's Soup to treat cancer have been done with small numbers of patients. These patients received other types of treatment, either before or during treatment with Selected Vegetables/Sun's Soup, and different vegetable mixtures were used in the different studies.
The results of these trials were compared with published information on similar patients who did not receive Selected Vegetables/Sun's Soup. Most patients receiving the vegetable mixtures lived longer, were better able to carry out their daily activities, and either gained weight or did not lose weight. In some patients who ate Selected Vegetables/Sun's Soup, tumor growth slowed or the tumor completely went away. Because patients in these trials received other treatments, it is not known if their responses were caused by Selected Vegetables/Sun's Soup, the other treatments, or both. None of the trials were randomized or controlled. Randomized clinical trials give the highest level of evidence. In randomized trials, volunteers are put randomly (by chance) into one of 2 or more groups that compare different treatments. In a controlled trial, one group (called the control group) does not receive the new treatment being studied. The control group is then compared to the groups that receive the new treatment, to see if the new treatment works. Randomized controlled trials, enrolling larger numbers of people, are needed to confirm the results of studies done so far on Selected Vegetables/Sun's Soup.
One randomized clinical trial (NCT00246727) of patients with stage IIIB or stage IV non-small cell lung cancer is now being conducted. The trial is comparing the survival of patients receiving Selected Vegetables/Sun's Soup with patients receiving a placebo (inactive substance). Both groups are receiving treatment with supportive care, such as radiation therapy, surgery, or palliative care.Have any side effects or risks been reported from Selected Vegetables/Sun's Soup?
No harmful side effects or risks have been reported in the use of Selected Vegetables/Sun's Soup. Some patients felt full or bloated after eating the dry form, but patients who ate the frozen mixture did not report this.Is Selected Vegetables/Sun's Soup approved by the U.S. Food and Drug Administration (FDA) for use as a cancer treatment in the United States?
The FDA has not approved any form of Selected Vegetables/Sun's Soup for the treatment of cancer or any other medical condition. Well-designed clinical trials that test identical mixtures of vegetables and herbs are needed to prove whether Selected Vegetables/Sun's Soup is useful in treating cancer.

General CAM Information
Complementary and alternative medicine (CAM)—also referred to as integrative medicine—includes a broad range of healing philosophies, approaches, and therapies. A therapy is generally called complementary when it is used in addition to conventional treatments; it is often called alternative when it is used instead of conventional treatment. (Conventional treatments are those that are widely accepted and practiced by the mainstream medical community.) Depending on how they are used, some therapies can be considered either complementary or alternative. Complementary and alternative therapies are used in an effort to prevent illness, reduce stress, prevent or reduce side effects and symptoms, or control or cure disease.
Unlike conventional treatments for cancer, complementary and alternative therapies are often not covered by insurance companies. Patients should check with their insurance provider to find out about coverage for complementary and alternative therapies.
Cancer patients considering complementary and alternative therapies should discuss this decision with their doctor, nurse, or pharmacist as they would any therapeutic approach, because some complementary and alternative therapies may interfere with their standard treatment or may be harmful when used with conventional treatment.
Evaluation of CAM Approaches
It is important that the same rigorous scientific evaluation used to assess conventional approaches be used to evaluate CAM therapies. The National Cancer Institute (NCI) and the National Center for Complementary and Alternative Medicine (NCCAM) are sponsoring a number of clinical trials (research studies) at medical centers to evaluate CAM therapies for cancer.
Conventional approaches to cancer treatment have generally been studied for safety and effectiveness through a rigorous scientific process that includes clinical trials with large numbers of patients. Less is known about the safety and effectiveness of complementary and alternative methods. Few CAM therapies have undergone rigorous evaluation. A small number of CAM therapies originally considered to be purely alternative approaches are finding a place in cancer treatment—not as cures, but as complementary therapies that may help patients feel better and recover faster. One example is acupuncture. According to a panel of experts at a National Institutes of Health (NIH) Consensus Conference in November 1997, acupuncture has been found to be effective in the management of chemotherapy-associated nausea and vomiting and in controlling pain associated with surgery. In contrast, some approaches, such as the use of laetrile, have been studied and found ineffective or potentially harmful.
The NCI Best Case Series Program, which was started in 1991, is one way CAM approaches that are being used in practice are being investigated. The program is overseen by the NCI's Office of Cancer Complementary and Alternative Medicine (OCCAM). Health care professionals who offer alternative cancer therapies submit their patients' medical records and related materials to OCCAM. OCCAM conducts a critical review of the materials and develops follow-up research strategies for approaches deemed to warrant NCI-initiated research.
Questions to Ask Your Health Care Provider About CAM
When considering complementary and alternative therapies, patients should ask their health care provider the following questions:
- What side effects can be expected?
- What are the risks associated with this therapy?
- Do the known benefits outweigh the risks?
- What benefits can be expected from this therapy?
- Will the therapy interfere with conventional treatment?
- Is this therapy part of a clinical trial?
- If so, who is sponsoring the trial?
- Will the therapy be covered by health insurance?

PDQ is a comprehensive cancer database available on NCI's Web site.
PDQ is the National Cancer Institute's (NCI's) comprehensive cancer information database. Most of the information contained in PDQ is available online at NCI's Web site. PDQ is provided as a service of the NCI. The NCI is part of the National Institutes of Health, the federal government's focal point for biomedical research.
PDQ contains cancer information summaries.
The PDQ database contains summaries of the latest published information on cancer prevention, detection, genetics, treatment, supportive care, and complementary and alternative medicine. Most summaries are available in two versions. The health professional versions provide detailed information written in technical language. The patient versions are written in easy-to-understand, nontechnical language. Both versions provide current and accurate cancer information.
Images in the PDQ summaries are used with permission of the author(s), artist, and/or publisher for use within the PDQ summaries only. Permission to use images outside the context of PDQ information must be obtained from the owner(s) and cannot be granted by the National Cancer Institute. Information about using the illustrations in the PDQ summaries, along with many other cancer-related images, are available in Visuals Online, a collection of over 2,000 scientific images.
The PDQ cancer information summaries are developed by cancer experts and reviewed regularly.
Editorial Boards made up of experts in oncology and related specialties are responsible for writing and maintaining the cancer information summaries. The summaries are reviewed regularly and changes are made as new information becomes available. The date on each summary ("Date Last Modified") indicates the time of the most recent change.
PDQ also contains information on clinical trials.
A clinical trial is a study to answer a scientific question, such as whether one treatment is better than another. Trials are based on past studies and what has been learned in the laboratory. Each trial answers certain scientific questions in order to find new and better ways to help cancer patients. During treatment clinical trials, information is collected about the effects of a new treatment and how well it works. If a clinical trial shows that a new treatment is better than one currently being used, the new treatment may become "standard." Patients may want to think about taking part in a clinical trial. Some clinical trials are open only to patients who have not started treatment.
Listings of clinical trials are included in PDQ and are available online at NCI's Web site. Descriptions of the trials are available in health professional and patient versions. Many cancer doctors who take part in clinical trials are also listed in PDQ. For more information, call the Cancer Information Service 1-800-4-CANCER (1-800-422-6237).
