Sisterhood has deep, evolutionary roots.

By Michelle Gallagher Escobar

Like the mycorrhizal networks beneath the forest floor, our survival has always depended on community.

Sisterhood is not a luxury.It is not simply for happiness or social wellbeing.

It is an ancient, essential bond—a key to resilience and healing.

The Science Beneath the Connection

Many equate oxytocin, the “bonding hormone,” with mothering—childbirth and breastfeeding.

But every woman releases oxytocin during times of stress.

This bonding hormone motivates us to seek nurturing connections.

It lowers cortisol, easing anxiety.

It improves mood.

It fosters feelings of safety and security.

This response has deep evolutionary roots.

Just as trees rely on the underground mycorrhizal network to share nutrients and communicate, women rely on sisterhood for survival and thriving.

Sisterhood Is Medicine

Sisterhood impacts not only our emotional well-being but also our mental and physical health.

When we gather, share, and hold space for one another, our bodies remember an ancient truth:

We thrive together.

Like the forest, we are more resilient in community.

It is in our roots as women.

Like the trees.

With warmth,
