Gecko is also called scorpion tiger, salty, cold, with a small poison. The old name “guardian”, “climbing gecko”, “climbing wall tiger”, “scorpion tiger”. “It is one of the “five poisons” in ancient times. The dried products of gecko are used in traditional Chinese medicine to nourish the lungs and kidneys, benefit the essence and blood, stop coughing and asthma, relieve spasm and dispel wind, and dispel swelling. Lymphatic metastasis is one of the common ways of tumor metastasis. At present, western medicine treats lymphatic metastasis with less drugs and unsatisfactory effect. Chinese medicine treats lymph nodes as phlegm-damp condensation, so it would be a big mistake if we simply know that lymphatic metastases can be lifted by using phlegm-dispersing drugs to treat them. First of all, lymph nodes are phlegm-dampness, the formation of phlegm-dampness is related to stasis, and stasis and phlegm-dampness are mutually causal. If the spleen and stomach are weak and unable to transport and transform, phlegm and dampness will not be easily eliminated from the lymph nodes. The gecko stinks, can wake up the spleen, dampness and stomach, some patients take gecko appetite increased, compared to other anti-tumor drugs hurt the stomach can not be said to be a major advantage. Gecko can dispel the wind, and has a better effect on primary brain tumors and metastatic brain tumors that are host to wind. We are familiar with the drugs that pass through the meridians, and we know that meridians are the channels that connect the internal organs, but this is only a simple concept and symbol in the brain. Most TCM doctors do not delve into the function that pass meridians can traffic the connection between internal organs. Tumor patients are often dysfunctional in multiple internal organs, so while adjusting the function of internal organs, they can often get twice the result with half the effort, and gecko has the function of channeling the meridians, which is not comparable to other drugs. If the tumor is superficial and large, it can be grinded into fine powder and mixed externally; if a sinus tract is formed, the tail of the gecko can be inserted from the small mouth of the fracture to treat the ulcer and take into account the drainage. It is necessary to recognize the different nature of heat and cold in different parts of lymph nodes. Metastasis to the neck, clavicle and mediastinum is phlegm-dampness and fire, so it is necessary to add heat-clearing and phlegm-transforming drugs such as cat’s claw herb, sea-floating stone and green pores; metastasis to the abdominal cavity is cold, so it is necessary to add warming and cold phlegm-transforming drugs such as white mustard seed, sliced sap, dry ginger; metastasis to the groin is related to liver cold, so it is necessary to add lychee kernel and orange kernel. Gecko can also treat esophageal cancer, gastric cancer, intestinal cancer, lung cancer, breast cancer, osteosarcoma, etc., has a good effect. Gecko dosage should be large, powdered punch 10 grams can be, the complete gecko decoction should be 30 grams. Gecko side effects are relatively small, the ancients with a copper spoon can be detoxified by simply frying.
