Lemongrass is the tall, sharp-scented stalk used across South and Southeast Asian cooking. The same compounds that give it that clean citrus bite — citral chief among them — make it a capable antifungal and a mild pain reliever.
For feet it earns its place two ways. Steeped into a soak it relaxes cramped muscles and takes the tension out of an arch that has been braced all day. And its antibacterial edge makes it genuinely effective against foot odour, which is not a hygiene problem so much as a bacterial one.
You can use the stalks from a supermarket, dried lemongrass tea, or the essential oil. The fresh stalk is cheapest and works perfectly well.
