Like a car, the human body often receives exterior washes but still requires interior cleansing to remove evidence of drive-thru dinners and stacks of unread user manuals. Clean your natural mode of transportation with this Groupon.

Choose Between Two Options

• $45 for a 90-minute initial colon-hydrotherapy session (a $90 value)
$65 for a 90-minute initial colon-hydrotherapy session and a 90-minute juicing class (a $49.99 value; a $139.99 total value)

To begin a client's initial colon-hydrotherapy session, a specialist leads a 30-minute consultation that includes a description of the 45-minute treatment to come. Once briefed on the processes and expected benefits, the client lies back while the professional uses temperature-controlled water to gently cleanse the large intestine. Clients may continue to detoxify in a juicing class, where an instructor explains the benefits of juices and smoothies and demonstrates how to make four of each.
