Kwench Juice Cafe Lake Oswego owners and baristas are not medical professionals and do not provide medical advice. As with any diet or exercise program, if you plan to juice cleanse for more than one day, please consult your physician before beginning. The Kwench Lake Oswego team does not diagnose or treat medical conditions, nor can we claim juicing/cleansing will cure or treat any medical conditions. We feel that juicing should be used in addition to any regular eating plan as a boost of vegetables and fruits.
