Cancer Research UK has compiled extensive scientific research on alternative therapies for cancer, including herbal therapy, yoga, chiropractics and homeopathy. This research has not produced significant evidence that herbal remedies can effectively treat cancer, according to the organization.
Due to the persistence of anecdotal success reports, many cancer patients choose to supplement their conventional cancer treatments with herbal remedies regardless of whether they have failed to demonstrate efficacy in a laboratory environment. Popular herbal remedies for cancer include aloe, St. John's wort, green tea and black cohosh, as stated by Cancer Research UK.
The American Cancer Society recommends that patients who are considering supplementing regular cancer treatments with alternative remedies consult with their physicians. They should also exercise caution when dealing with therapies that promise to cure cancer.
