Sodium bicarbonate can be used quite strongly to combat Candida and cancer in the colon. I recommend starting with 1/8 cup of bicarbonate in a full quart of water and working up gradually to ½-cup maximum. Seawater is great for this application but seawater alone is better used for long-term therapy and also because the real point to irrigating seawater into the colon is to get it into the blood as if one were doing an IV.
Sodium bicarbonate enemas can be started gradually, perhaps once every other day for candida treatment and up to 3x/day when doing intense sodium bicarbonate treatments for colon cancers. Always check your pH daily and keep within safe parameters of 7.3-7.4 unless cancer is being treated and you are aiming for pH of 8. Use less frequently once pH gets to 8. Length of use will depend on severity of infection and relief of symptoms.
In cancer treatments sodium bicarbonate can be instilled closely to tumors in the uterus, colon and GI tract with enemas. The procedure adopted by Dr. Simoncini called TAT should be utilized. Unfortunately very few doctors have been able to adopt the Simoncini protocol successful.

 “Those practitioners who administer colonic therapy properly are offering a useful service to the public. This service can be greatly enhanced with the addition of sound dietary counseling so as to eventually overcome the need for colonic therapy. Without this knowledge, the colonic recipient is merely digging holes and filling them again—a net zero toward building a better health quality.” http://detox.net.au/enemas-for-bowel-health/
