Saffron, often called "red gold,” is the world’s most expensive spice, prized for both its flavor and potential health benefits. Its active ingredient is called crocin. In this report, blogger and medicinal herb specialist Isabel Fischer shares recipes for saffron milk and an oxymel mocktail, which she says help lift her mood. Pharmacists offer saffron extracts as dietary supplements for mild low mood, while medical experts say studies suggest saffron may help with mild depression, anxiety and stress-related sleep problems, although more evidence is needed for conditions such as ADHD, menopause and PMS. Experts also warn that very high doses can cause serious side effects, so it is essential to follow expert advice and use it only in moderation.
