Many eczema treatments require topical care, but this one has more to do with what you ingest. Studies have linked this spice to reduced inflammation in a number of skin conditions, including psoriasis. Curcumin, an antioxidant found in turmeric, has been shown to protect skin by neutralizing free radicals and reducing wound-healing time. To achieve benefits, aim to take in about a teaspoon of turmeric every day. It has a subtle, citrusy flavor that works well with rice, veggies, pasta, and other cooked meals.
