Nature has products to boost our immunity

Our body has the natural ability to give a fighting reply to disease causing germs, bacteria, virus and other factors. The white blood cells present in the bloodstream plays the role of the fighter. This immunity tends to decrease with age and other factors. Most of the medicines and antibiotics treat the disease by increasing the immunity of the body against the respective disease. Here we can see that we prefer medicines to treat the ailment or in other words to increase the immunity. Remember, these medicines are not according to nature’s pattern which defines the human body. Our body is a natural product and responds best to any natural treatment and natural booster. This is not against any medicine; there are cases where natural therapy looses to clinical methods. But the natural methods have an upper hand. Our kitchen has some food and natural products which increase the immunity of the body (immunity booster) and keep the body and mind healthy. In this article, you will come to know the properties of food which are responsible for better immunity of the body.

Functions of our body

Know our immune system

Our immune system is a combination of many functions and whose only goal is to protect our body from unhealthy conditions by warding off disease causing germs and bacteria. It is like an orchestra which has many instruments and only one goal. Our immune system has cells circulating in the bloodstream, or in the lymph nodes. These are present in every part of the body. The immune cells are positioned in your body in such a way to prevent the entrance of any invader, whenever it is called upon. The immune system has lymphocytes or T-cells which fights the disease causing germs and bacteria. It also has B-cells which help in the formation of anti bodies that act against the invading molecule and toxins. Your immune system also has phagocyte cells, like macro phages and neutrophilis. Its main function is to clear the debris and waste created from the dying or destroying cells. Your immune system has also soluble factors which can recognize the area from where your body has been invaded and then helps in treating that particular area. We can see that immune system has complex functions which have to be at the optimum level at all the time. It is a system that involves our whole body and needs to be maintained preferably by natural methods. Natural methods are slow but have permanent effect.
