The immune system is the human body’s defense mechanism against all the infectious micro-organisms and pathogens.
It is made up of special cells and organs that work together for defending the human body from contracting diseases.
The leukocytes are the special cells, and the primary defense organs are so-called lymphoid organs.
Meanwhile, the leukocytes circulate the human body through blood vessels. It's also the body that protects us against foreign substances and infectious diseases.
So, the immune system is therefore responsible for keeping us healthy.
How The Immune System Works?
The Immune system guards your body against substances it detects as harmful bacteria, virus fungi and toxins. These substances are called antigens.So, when the immune system recognizes an antigen entering the body, it tries to destroy them.
This is what we call an immune response. Our immune system is connected to our organs, cells and proteins that work together to make antibodies. These antibodies serve as an army to protect, destroy and weaken antigen that cause infection, illness and disease.
Subsequently, the immune system remembers the antigen. If ever it enters again in the body, it is easily recognized and sends antibodies, in that case, you may won't get sick. The capability of our body to protect ourselves from certain diseases is what we call immunity.
What makes the immune system weak?
The immune system works to protect human beings from contracting diseases; however, when it fails to do its job, illnesses and infections are the final result.
Although some things make the human system weak, including stress, lack of exercise, extreme hygiene habits, poor nutrition, dehydration, and drug consumption, most of these factors are external and can be managed to prevent the immune system from weakening.
Stress is an emotional factor that most people underplay. In fact, when you experience stress, your body responds by releasing cortisol from the adrenal glands to manage the stress.
Hence, an increase in the level of cortisol in the body causes a decrease in the production of prostaglandins, which helps in supporting the immune system.
In addition, this leads to the suppression of immune functions and the inflammation of several body organs. (Holtorf Medical Group, 2018).
Immune System Decline As We Age
As we age, the capability of our immune system may not work as well, and responds very slowly. This increases the risk of getting sick. Although some people age healthily, there are some studies that show the immune system comparison to elderly and younger people.
Elderly people are more likely to develop infections and diseases that are more likely to be the cause of death. In fact, even those influenza vaccines efficacy may be reduced. That means it is less effective compared to healthy children.

Also, these compounds work by stimulating the body’s immune response system and by preventing the replication of harmful bacteria and viruses (Comvita, 2016).
This is also another herb that has gained popularity for its ability to fight colds and other infections. It contains a mixture of active compounds that are perceived to be antimicrobial.
Furthermore, all species of Echinacea have phenols that are very effective antioxidants.

Berberine is a constituent of different plants such as Chinese goldthread, Goldenseal, Oregon Grape, and Barbery.

For instance, it helps in fighting diabetes; It also improves cholesterol levels, helps with weight loss, reduces inflammation, and it is an anticancer agent (Cohen, 2016).
Lastly, elderberries. These are the fruits picked from the Sambucus tree.
They have been used throughout history by Native Americans and Europeans to deal with a range of health problems, such as fighting off colds.
They are also an excellent immunity booster. In fact, a study conducted in 2010 suggested that elderberries contain chemical substances that have an antiviral effect. Therefore, these chemical components help attack cold and flu viruses.
