Guava or guava drink is used in some countries as medicine, because it is very rich in Vitamins A, B, C potassium, fibres and iron.
Its Vitamin C far exceeds (5 times more) that of orange extracts, hence it treats coughs, colds and scurvy.
As for the fruit and mostly juices as well, there are arrays of benefits in treating high blood, high cholesterol and congestion in heart and lung.
One may also find these beneficial effects from one or another fruit or fruit juice but guava appears to have more to offer.
No wonder it has earned its name as multi-purpose healer.
