Allergies and the Nervous System: Calming Herbs for Yearlong Resilience

Seasonal allergies are often framed as a localized immune problem—something that happens in the nose, sinuses or lungs. But holistic practitioners see them as a whole-body experience shaped by stress, nourishment and environment. Linda Conroy, a bioregional herbalist with more than three decades of experience, uses native medicinal plants in a three-tiered approach that focuses on prevention, tonification and support. Tonification aims to nourish, strengthen and restore balance to the body’s vital energy.

“You’re not going to take one herb and have it fix everything,” explains the founder of Moonwise Herbs. “You have to work on diet, lifestyle, relationships and stress reduction. It has to be multilayered.” Rather than suppressing symptoms, Conroy works to strengthen the body’s baseline resilience so that when pollen counts rise or seasons shift, it is equipped to respond.

The Role of Stress

All parts of the body are interconnected. When the nervous system is stressed, other systems are affected. We see this with asthma, says Conroy, citing research that links prenatal and early-life stress to respiratory vulnerability later in childhood. “When someone’s respiratory system is in distress, we have to work with all the systems of the body to address it,” she explains.
