Nurse Practitioner Irina Serebryakova will introduce the 21-day Purification Cleanse from 6:30 to 7:30 p.m., January 11, at Groton Wellness, in Groton. The three-week program is specifically designed to safely, slowly and effectively detoxify the gastro-intestinal system, liver, gallbladder and kidney, and can lead to improved circulation,sleep patterns, hormone function, overall health, weight loss, and reduce allergies, headaches, and joint and muscle pain.

Participants will eat a modified diet (depends on each individual’s needs) usually consisting of only whole foods (no processed foods or artificial sweeteners), and take fiber and cleansing supplements, all of which are made from food, without any herbs or artificial ingredients. Those taking lithium drugs or blood thinners such as warfarin and coumadin are not advised to participate in the program.

According to Serebryakova, most patients lose an average of 10 to 15 pounds during the program, and because no fasting is involved, she maintains participants should never feel hungry during the three weeks. All supplements, shakes, guidelines, recipes and online support are included.

Cost: $255 regular price; $200 at the time of presentation. Location: Mill Run Plaza, 493-495 Main St., Groton. Registration for the Introduction class is optional but suggested. For more information or to register, call 978-449-9919 or visit GrotonWellness.com.
