Individuals may call 210-366-2888 or use the online referral feature that I-ACT.org provides, as of 2015, to find a colonic provider. The referrals include contact information, training and certification levels. The listed colonic hygienists receive training from I-ACT, which recommends the use of FDA-compliant equipment, disposable supplies and filtered water.
Colonic hygienists in 20 states and six countries listed online by the Natalia Rose Institute include only those who use gravity methods instead of pressurized methods. The contacts include some colonic hygienists who use the LIBBE method. A state-licensed medical practitioner must direct the purchase and use of the LIBBE system.
