A lymphatic drainage stimulant is disclosed, which is produced by -providing drinking water that meets predetermined requirements, and -treating the water with a baro-membranous system. The treatment includes passing the water through a semi-permeable reverse-osmosis membrane made with a hole size 0.0001-0.005 μm, so that the water acquires the following parameters: a redox potential ranging from +200 to +343 mV, total mineralization ranging from 25 to 130 mg/L, and pH index ranging from 6.9 to 8.3. A proposed method for preparation and administering of the stimulant includes saturating the water with macro- and microelements. The stimulant can be administered for medical treatment of patients with chronic skin diseases, non-oncological diseases of gastrointestinal tract, and chronic obstructive bronchitis. In such case, the stimulant is preferably taken 30-40 minutes before and 2-2.5 hours after each meal, altogether 1.5-2.5 L a day, and the first dose is taken during the morning fast.
