Nature plays an important role in the growth and preservation of life on our earth and it also plays an important role in the healing of many diseases...
Many a times when I am effected with common cough and cold, only a few leaves of the Tulsi plant in the morning comes in handy and cures me from the infection...
I am generally healed by nature. when you feel some physical disorder, just listen to your body. You will be okay. For example, fever directs you to rest. Rest for some time will cure fever. Indigestion will be cured by abstaining from eating for some time. Cold and cough will be cured by taking hot stuff like coffee, chicken soup etc.
Nature is a friend of mine. It is the fresh air from the trees which refreshes both my body and mind when i am tired. It is the chirping birds which wakes me up when i am overslept. Nature is so nice.
