Wound healing is the process of natural skin repair influenced by blood supply. If the supplied blood is contaminated by infecting organisms or if a person is diabetic, wound healing will be delayed and may lead to secondary infections. To purify the infected blood and to enhance the natural healing process, vallarai powder can be taken internally and applied externally over wounds as well. For wounds that have not healed for a long time now, the best solution is to apply ground Vallarai on the affected area and to wrap it up with a bandage.
After a heavy meal or followed by an antibiotic course, stomach upsets are normal. These factors increase the internal heat (Pitta) and cause ulcers in gastro intestinal tract which leads to gastritis, diarrhea and dysentery. To get rid of these complaints, making a paste of 3-4 vallarai leaves along with cumin seeds, and then mixing it with sugar and gulping the mixture down will prove to be beneficial. According to Ayurveda,Vallarai pacifies Pitta and arrests diarrhea and dysentery.
Fever or raised body temperature is actually a signal that indicates the immune response of the body against the entered microorganism is slowly being defeated. Usually it lasts for 2-3 days, but if the microorganisms are very strong or if the immunity of the individual is not strong enough to destroy them, fever lasts for more than 3 days. However, it should not be ignored if it lasts more than three days. To improve the immunity of a person and to destroy the microorganisms, one could use a paste of Vallarai, Tulasi (Basil) and Black pepper mixed in equal quantities and ground finely. This paste can be consumed twice daily for the body temperature to return to normalcy.
