Among all plants available on the market and coming directly from our nature, goya is the one to pay attention to. Otherwise known as karela, this cucumber-shaped plant does wonders for the human health. It grows in South America and Asia, and requires warm and humid climate to grow. Among the many things it cures, you will be happy to learn that it is excellent for treating cancer, too. The man behind this discovery is Dr. Frank Shallenberger, a doctor specialized in anti-aging treatments and alternative medicine. As he states, karela can suppress the development of cancer cells, so he regularly recommends it to patients who are dealing with this disease. As numbers show, karela kills off about 90-98% of all cancers cells formed in the human body, which is astonishing information. The University of Colorado conducted a study which analyzed the goya effects on the human body, especially with cancer. The findings uncovered that a 5% goya solution reduces pancreatic cancer and almost 64% of pancreatic tumors.
