The word inoculate means to implant (a disease agent or antigen) in a person, plant or animal, so that the stimulating of a disease resistance may occur in the body. 

to imbue (a person), as with ideas.

in·oc·u·late verb, in·oc·u·lat·ed, in·oc·u·lat·ing, inoculation.

(putting or injecting a little bit of an infected chemical or bacteria into a plant, animal or person), so that the immune system can be able to build up antibodies that can resist that type of bacteria.

There are many types of bacterias that surrounds our environment, bacterias which are produced by industrial chemical pollution, seasonal changes, socializing of people that comes from different nations, etc.

When ever the body is confronted or attacked by a new bacteria, inoculation takes place in the body. The body will immediately begin to build up new antibodies that will defend it from that new bacteria. 

Inoculation is also done through Vaccinations, medication given to people during the changing of seasons, allergies etc.

The body which lacks herbal nutrients and organic veggies or a person that doesn’t eat enough herbal nutrients (veggies) will end up suffering from long time prolonged diseases, infections and sicknesses during the seasonal changes, and times when new bacterias are introduced into his/her environment.
