Onosma bracteatum, commonly known as "Gaozaban," has a long history of use in Unani and traditional Ayurvedic medicine systems. In these traditions, it is attributed with a variety of medicinal properties, including mild sedative, anti-inflammatory, and demulcent effects. Its use for colic in children, however, is primarily grounded in folk and traditional practices, where herbal infusions or decoctions of the plant are sometimes administered to soothe digestive discomfort and abdominal pain. Texts from traditional medicine may mention its use for general gastrointestinal complaints, but they rarely provide detailed, direct evidence relating specifically to infantile colic.

There is a lack of modern clinical trials or robust pharmacological studies directly evaluating the efficacy or safety of Onosma bracteatum for the treatment of colic in children. Most available evidence is anecdotal or comes from historical texts rather than systematic scientific investigation. As a result, the evidence level supporting its use for this condition is very low (rated 1), reflecting tradition rather than scientific validation. Parents and caregivers should exercise caution, as safety and dosage parameters for children have not been established in the scientific literature.
