Due partly to the increase in germs being brought home by children attending school, and partly because of other seasonal factors, right now is a great time for germs and contagious illnesses.
Because of this, there is no time like the present to work on strengthening your immunity and that of other members of your household.
Echinacea is probably the herb best known for this action. And it does work-- for a short period of time, and in people who are otherwise healthy. Echinacea is like coffee for the immune system. It wakes it up and makes it act more energetic for a relatively brief period of time (maybe 2-4 weeks), after which it sort of loses its effect. Also, it should be noted that people with certain conditions (such as rheumatoid arthritis) should not take echinacea.
Astragalus is another herb which is widely used for strengthening the immune system. It can be used for a longer period of time. Its main mechanisms of action include causing more immune system cells to be produced, and essentially providing nutrients for these cells. Astragalus has a very long documented history of use, and has been the subject of much modern research.
Usnea is another type of herb with immune system benefits. It contains substances that destroy or halt the actions of viruses and bacteria, and other substances which nourish the cells of the immune system.
These are just a few examples of the dozens of herbal remedies that can be used to bolster the immune system. I can work with patients to individually address the particular needs of their immune system, based on their body type, existing conditions, and other relevant factors.
