And while those things may help, the plants in your grandmother's herb garden might also be of use. Dr Cuellar says he's a supporter of "bush medicine" but added that it is most effective when combined with more conventional medicine as well. So while your ginger tea can help with a cough, combined with the vaccine, it can greatly lessen your symptoms.

Dr Fernando Cuellar, Internist

"There is a role for herbs for sure. But we need to also understand that we can combine conventional medicine with your herbs. There's a lot of things that are used to boost immune system, that's fine, even after getting the disease it helps for your lungs to recover so I am one of those who do endorse herbal medicine as a part of the holistic treatment."
