Tea brewed with winter melon rind, lotus leaf and rose flower may have the effect of diuretic, relieving heatstroke and depression, but the above herbal infusions may not be able to completely precipitate the active ingredients of the drugs, so the efficacy is limited.
Winter melon peel can diuretic and reduce swelling. It is used for edema and distension, dysuria (unsmooth urination), summer-heat thirst, and short and red urination (small amount of urination with dark yellow color).
Lotus leaf can clear summer-heat, eliminate dampness, elevate Qing-Yang (conveying nutrients from digested food to the head and face, etc.), cool blood and stop bleeding. It is used in treating summer-heat and thirst, summer-dampness and diarrhea, diarrhea due to spleen deficiency, epistaxis due to blood-heat (vomiting of blood and nosebleed due to blood-heat), and bleeding in stool and leakage of urine (excessive menstrual flow or dribbling).
Rose can move Qi, relieve depression, harmonize blood and relieve pain. It is used for liver and stomach qi pain, poor appetite and vomiting, irregular menstruation, bruises and injuries.
It is recommended to use the medicine under the guidance of a doctor.
