Viola Odorata L.

Sweet violet is a medicinal plant used in traditional Persian medicine (TPM) for various conditions, including hair loss, eczema, and headaches. It contains compounds like mucilage, anthocyanins, and flavonoids. Violet syrup is beneficial for asthmatic coughs and constipation in children, while oral or nasal administration aids insomnia. Nasal violet oil can alleviate allergic rhinitis and dry eyes, and topical application can reduce fever, repel insects, and relieve uremic pruritus in dialysis patients. No significant side effects are noted at therapeutic doses, but high doses may cause adverse effects like nausea and anxiety.
