Skin allergies

Wash and grind 500g unripe persimmon. Place in a large bowl. Add 1.5 liters water, mix and leave out in the sun for seven days. Throw away the solid residue and keep the water. Leave the water in the sun for a further three days and then pour into a jar. Use a piece of cotton wool to apply the liquid four times a day to areas where your skin suffers from allergies or is particularly sensitive (It doesnt explain what you do for the 10 days while the persimmon juice is out in the sun, and how you have it out in the sun but not in the rain, and how you stop the local dogs and tigers from drinking it).
