    What Is Chorus?

    The herbal formula that bridges the gap between antibiotics and probiotics — built to balance the microbiome you already have, not wage war on it.

    The Short Answer

    A third option for your gut

    Your gut shapes far more than digestion — it influences immunity, mood, sleep, and mental clarity. When it's struggling, you feel it everywhere. For most people, the only options on offer are antibiotics that kill bacteria or probiotics that add them. Both treat the microbiome as something to be controlled from the outside.

    Chorus is a third option. It's a small-batch herbal formula inspired by the classical Chinese formula Bao He Wan — designed to restore balance to the bacteria you already have. Rather than carpet-bombing or flooding the gut, it works on the terrain: clearing stagnation, supporting digestion, and helping your own beneficial microbes recover. After 20+ years in practice, this is the approach I trust for lasting change.

    "Antibiotics subtract. Probiotics add. Chorus does something harder and more useful — it helps the ecosystem you already have come back into balance."
    — Brehan Crawford, MAcOM, LAc
    How Chorus Works

    Nature's answer to a balanced gut

    Chorus nurtures an environment where beneficial bacteria can thrive while keeping less helpful microbes in check — a more harmonious gut ecology. It's built on two principles: respect the classical formula, and use high-quality botanicals.


    Rooted in Bao He Wan

    A classical Chinese formula used for centuries to resolve food stagnation and restore healthy digestion.


    Small-batch botanicals

    Crafted in small batches with high-quality herbs, often sustainably sourced from small farms.

    Inside the Formula

    Ingredient highlights

    Astragalus

    Traditionally used to support immunity and the gut lining.

    Licorice Root

    Soothing to the digestive tract; a classical harmonizing herb.

    Ginger

    Warming; traditionally used to ease bloating and support digestion.

    Peppermint

    Calming to the gut; often used for IBS-type discomfort.

    Atractylodes

    A chief Spleen-supporting herb for digestion and motility.

     Research Spotlight

    An old herb, measured with modern tools

    A 2024 study in Neurogastroenterology & Motility found that polysaccharides from Atractylodes reshaped the gut microbiota and influenced serotonin (5-HT) signaling in a model of "Spleen deficiency" — reducing transit time and improving stool output. It's a concrete example of a classical digestive herb acting along the gut-brain axis.
