Spikenard (Nardostachys jatamansi) has a long history of use in traditional medicine systems, particularly in Ayurveda and traditional Chinese medicine, where it has been employed to support various skin conditions, including infections, wounds, and inflammation. Traditionally, the essential oil or paste derived from Spikenard roots was applied topically to treat skin ailments, believed to possess antibacterial, antifungal, and anti-inflammatory properties. Historical texts often describe its use for calming skin irritation and promoting wound healing.

Scientific evidence for these effects is limited but not entirely absent. Some in vitro studies have demonstrated that extracts and essential oils from Spikenard exhibit antimicrobial activity against certain bacteria and fungi. For example, research has shown activity against bacteria such as Staphylococcus aureus and fungi like Candida albicans. However, these studies are preliminary, often restricted to test tubes, and do not provide conclusive evidence for clinical efficacy in humans. There are very few, if any, well-designed clinical trials confirming its effectiveness for treating skin infections.

In summary, the use of Spikenard for supporting skin health and treating skin infections is primarily grounded in traditional practices, with modest scientific evidence suggesting potential antimicrobial activity. More rigorous human studies are needed to substantiate its efficacy and safety for these applications.
