Since early times, Asian traditional homeopathic practitioners have used mulberry leaves as herbal remedies. They prescribe mulberry leaf tea to treat fevers, coughs, sore throats, neurosis and thirst as well as to reduce sugar levels in blood and blood pressure. It is also recommended to treat skin ailments and tearing eyes, dizziness and headaches. It has been used to stimulate urination and bowel movement.
The mulberry leaves for making tea are harvested from our own plantations which are under an optimal agrotechnics. The mulberry plantations are completely isolated of possible pollution with agricultural chemicals or any other harmful for the people and animals substances. Therefore the mulberry leaves obtained are entirely ecologically clean. The leaves are picked up during the period June – September. Only high quality and completely healthy mulberry leaves, having high nutritive content are selected for tea making.

Still, if one were to ask how many cups, or glasses, of mulberry leaf tea they should drink per day and at what times, there is no clear answer as there are no studies which have provided either positive or negative results for amounts imbibed. Some will say, mulberry leaf tea should be taken between or following meals, but again no one is certain when the most benefits can be attained.
