Basti (Medicated Enema): Risks and Evidence

Safety first

Basti is a procedure in which medicated liquid is given as an enema. This page describes it and gives no instructions, volumes or preparations. Do not try it at home. NCCIH says colon-cleansing procedures may have side effects, some serious, and that harm is more likely with a history of bowel disease, colon surgery, severe hemorrhoids, kidney disease or heart disease. [1] That statement is about colon cleansing in general, not basti specifically. Seek urgent care (911 in the US) for severe abdominal pain, bleeding, fever, fainting or confusion. Poison Help (US): 1-800-222-1222. [2]

What basti is

Basti is an enema-based Ayurvedic treatment; reported forms include niruha basti (a decoction enema), anuvasana basti (an oil enema) and uttara basti, a "urethral douche". [3] [4] It is one of the panchakarma procedures; see the overview and procedure list. Its traditional explanations rest on dosha ideas, which are frameworks, not measured biology. Oil enemas have also been tested as a gentler way to do the oiling that usually precedes vomiting or purging. [5]

What research shows

All of these are unblinded pilots or reports, run by Ayurvedic institutions, so expectation and other changes (such as diet advice that came with the program) may explain part of any improvement. One of the obesity studies also gave diet and lifestyle advice to every group. [6] Reporting of harms in Ayurvedic trials is limited. [8]

Risks and who should avoid it

• Bowel and rectal problems: harm from colon cleansing is more likely with bowel disease, surgery or severe hemorrhoids. [1]
• Fluid and salt balance: enemas and laxatives can cause diarrhea, which can cause dehydration. [1]
• Uttara basti involves other body openings. We found no safety study, so it should only be considered with a licensed medical clinician's advice.
• Product quality: some Ayurvedic preparations contain toxic metals. [9]
• Pregnancy, nursing, children and older adults: ask a clinician first. [9] [10]

Questions to ask before considering it

• What training and credentials do the people giving it hold, and which regulator or professional body stands behind them?
• Will a doctor review my health history and medicines first, and who checks my blood pressure, fluids and blood salts during the course?
• What would make you stop, and where do I go if I feel unwell?
• Where do the herbal products come from, and have they been tested for metals?
• Which of the claims you make are based on trials, and which on tradition?

Practitioners and regulation

US: no significant regulation of Ayurvedic practice and no state license. [9] India: formal degrees exist, but no national online register of practitioners has been described. [11] See Choosing an Ayurvedic Practitioner and Panchakarma Safety.
