Oat decoction, I use it myself and recommend it to you. Cough, Bronchitis, Flu, Immunity, Stomach...
This forgotten folk remedy will get you back on your feet, relieve constipation, rejuvenate the body, and help you lose excess weight (obesity). It will normalize blood pressure, clear pustules and acne from your skin, restore normal sleep, strengthen the cardiovascular system (heart attack, stroke), and restore normal gastrointestinal function. It will also help cure rheumatism.
