Reading Time: <1 minute We performed high-concentration vitamin C infusion on a patient who came by referral. The infusion was intended to reduce side effects as much as possible before chemotherapy for malignant tumors. In the past, my father-in-law imported it personally as an alternative treatment for lung cancer 10 years ago. Currently, it is performed for the purpose of rejuvenation. Recently, evidence is being established and it may be evaluated as an excellent treatment. It would be great if anti-cancer treatment without side effects becomes widespread. For anti-cancer treatment, 50-100 grams, and for anti-aging treatment, 12.5-25 grams. The infusion takes 1 to 3 hours, and there are almost no risks other than slight vascular pain.
