Steamed eggs with cactus is a food, and the cactus itself has the effect of clearing heat and removing toxins, dispersing blood stasis and swelling, and strengthening the stomach and relieving pain, but it has no effect on the treatment of cancer. Negative ion therapy can be used in conjunction with traditional treatments for cancer treatment. Negative ion therapy is a natural therapy, which has no toxic side effects on human body, while drug therapy is different. Negative ion therapy is different, it is the first to ensure that there is no toxic side effects, that is, naturopathy and drug therapy treatment concept is completely different. Naturopathy avoids using any factors that weaken the body's self-healing power to treat the disease, while drug therapy first considers the therapeutic effect on the disease, ignoring the therapeutic effect outside of the human body is very harmful to the production of toxic side effects.

According to the clinical experiment report published in 1994 by "China Tumor Clinic", which was made by medical scholars Li Keliang, Zhao Yongquan, and Wang Xianglin, a large number of animals may not develop metastatic tumors in the lungs if they inhale a large number of negative ions in the air every day. Primary tumor is also inhibited, early application is much higher than late application, but late application also has certain effect. Therefore, it is a promising beginning to control tumor metastasis, and it is simple and easy to implement without any damage to the organism. The name of the literature report, "Preliminary report on the experiment of cancer metastasis inhibition by negative air ions".

Numerous medical researches and clinical tests have proved that: the electron of human cells is snatched as the source of all diseases, and the reactive oxygen (free radical) is a kind of substance which lacks of electron, and after entering into human body, it scrambles for the electron everywhere, and if it snatches away the electrons of the cellular protein molecules, it can make the proteins connected to the branched chain to be alkylated, and form the aberrant molecules and cause the cancer. And when the free radicals or aberrant molecules rob the genes of electrons, people will get cancer directly. After the human body gets negative ions, because negative ions are negatively charged with excess electrons, a large number of electrons can be provided, and the vicious cycle is blocked, and cancer cells can be prevented or inhibited. In addition, negative ions can regulate acid-base imbalance and redox imbalance caused by malignant tumors, maintain the stability of the body environment, promote normal cell metabolism, alleviate and eliminate the negative effects of chemotherapy, which is very beneficial to the treatment of patients.

Negative ions in the air can be divided into large and medium-sized ions according to the size of their mobility, in which the small ions that is the small particle size of negative oxygen ions, has a high activity, the migration distance is far away from the characteristics of the negative ions in the air is equivalent to the nature of the air, also known as ecological level of negative oxygen ions. Medical research has proved that only small particle size negative ions are easy to pass through the human blood-brain barrier and provide medical care for the human body. At present, the negative ion health instrument through the use of the world's leading negative ion converter technology and nano fullerene negative ion releaser technology, can be artificially generated particle size, high activity, migration distance of the ecological level of negative oxygen ions, and the release of high concentration, there will be no ozone, positive ions and other derivatives.
