Good scientific evidence
- Colonic irrigation/colon therapy
: Irrigation of the colon for therapeutic purposes may have been used as early as ancient Egypt, China, India, and Greece. This practice gained popularity in 19 century European spas, and has been used in modern times to promote general well being and to treat multiple health conditions. Colonic irrigation may be used in patients with ostomies (post-surgical connections of the intestines to the side of the body). This procedure should be performed by or under strict supervision of a qualified ostomy healthcare provider.

Unclear or conflicting scientific evidence
- Cranberry
: It is proposed that skin irritation at urostomy sites may be related to urine pH. Cranberry juice
(Vaccinium myrtillus) can lower urine pH, and has been tested for this purpose. Further study is needed.
- In theory, due to its acidic pH, cranberry juice may counteract antacids. Cranberry juice theoretically may increase the effects of antibiotics in the urinary tract and increase the excretion of some drugs in the urine. Cranberry juice may increase absorption of vitamin B12 in patients using proton pump inhibitors such as esomeprazole (Nexium®). Although controversial, some studies have shown that taking the prescription blood thinner warfarin (Coumadin®) and cranberry products at the same time can elevate the INR, which could increase the risk of bleeding.
