IBS symptoms

Limited Evidence

Small clinical trials report improvements in bloating, gas, and abdominal pain with asafoetida-containing products.

How it works

Asafoetida contains sulfur-containing volatile oils, ferulic acid, umbelliferone, and resin components. Traditional use targets carminative (gas relief), antispasmodic, and expectorant effects. Preclinical studies suggest antimicrobial, anti-inflammatory, and antispasmodic activity. A few small clinical trials report benefits for IBS symptoms; the broader evidence base is limited.

Dosage

Culinary use is a small pinch per dish. Therapeutic doses in clinical use range from 50 to 250 mg of standardized extract per day.

When and how to take it

Take with meals to support digestion. Therapeutic doses are typically split twice daily.
