Lymphatic Enhancement Therapy (LET) is NOT the same as Manual Lymphatic Drainage. LET focuses on relieving congestion in the major lymph node areas of the body from head to foot. In addition, visceral work performed on the liver, spleen, lungs and intestines help to jumpstart the healthy functioning of your lymphatic and immune systems. Great at helping to relieve unexplained pain, bloating, brain fog, fatigue, and swelling and can even help enhance weight loss.
