Spiked Ginger Lily (Hedychium spicatum) has a history of traditional use in Ayurvedic and other folk medicine systems, particularly in South Asia, for treating various respiratory ailments, including congestion and sinus issues. The rhizome of the plant is commonly used in formulations or as a decoction, with practitioners claiming benefits such as clearing nasal passages, reducing mucus, and easing breathing difficulties. Historical texts and ethnobotanical surveys document its use for coughs, asthma, and sinus congestion, often attributed to its aromatic and expectorant properties.

However, while traditional use is well established, modern scientific studies directly assessing the efficacy of Spiked Ginger Lily for sinus congestion or related respiratory conditions are limited. Some laboratory studies have identified antimicrobial and anti-inflammatory compounds in the plant, which could theoretically contribute to relief of congestion, but clinical trials in humans are lacking. In summary, the support for Spiked Ginger Lily in sinus congestion is primarily based on traditional use, with only limited preclinical scientific investigation and insufficient clinical evidence.
