Onosma bracteatum, commonly known as "Ratanjot" or "Gaozaban," has a longstanding presence in traditional Unani and Ayurvedic medicine as a remedy for respiratory issues, including colds. Historical texts and ethno-medicinal literature document its use for soothing sore throats, coughs, and other symptoms associated with upper respiratory tract infections. The plant is often prepared as a decoction or herbal tea, believed to have demulcent (soothing) and mild anti-inflammatory properties that can alleviate irritation in the throat and airways.

However, scientific evidence substantiating its effectiveness for the prevention or treatment of colds is limited. Some laboratory studies have identified antioxidant and anti-inflammatory compounds in Onosma bracteatum extracts, but these findings are preliminary and not specific to viral respiratory infections. Most available research focuses on its general anti-inflammatory and antimicrobial activity, without direct clinical trials or in-depth studies on its impact on the common cold.

In summary, the use of Onosma bracteatum for colds is primarily rooted in traditional practice, with modest pharmacological rationale but insufficient rigorous scientific validation. It remains a common component in traditional remedies, but more well-designed studies are needed to confirm its efficacy for cold prevention or treatment.
