April 17, 2023

For centuries, before the development of modern antibiotics, herbs were the primary tool used to support the body's natural immune defences. While prescription antibiotics are essential for treating serious bacterial infections, their overuse can impact our gut microbiome, where 70-80% of our immune system resides. Herbal remedies offer a way to support our bodies naturally, especially during times of seasonal ills and chills. Unlike antibiotics which target bacteria only, many herbs provide broad-spectrum benefits that help you recover and build resilience. Here are five of the most effective herbs for supporting your health.

Introduced into standard medical practice in the United States in the 1800s, echinacea was a popular anti-infective medicine. That was until the development of antibiotics, where its use fell out of favour.

If you are susceptible to seasonal infections, echinacea can be used as prevention support. As echinacea supports the immune system, it is important to note that patients being treated with auto-immune conditions should avoid it unless they have been told otherwise by a health professional.

Bees pollinate the manuka bush, and the product provides antimicrobial properties. Traditionally, manuka was used to reduce fever, as a sedative, pain reliever, and to aid urinary conditions. Antimicrobial and immune supporting in nature, manuka is an effective support for seasonal infections. Manuka’s astringent properties means that it is also a great topical preparation.
