It has been widely used as a blue dye in eastern China, the Korean Peninsula, and central Japan. Indigo, cherished as a medicinal herb, has protected people's lives. It has antibacterial effects on heat rash, rashes, and skin diseases, and is also effective for cold sensitivity. It has also been confirmed to contain antioxidants and antibacterial substances. [Care Instructions] As plant-based dyes are sensitive to ultraviolet rays, we recommend storing them in a dark place. For washing, we recommend hand washing without using bleach or detergents containing fluorescent agents. Please do not wash with white items as the color may fade. Also, plant-based dyes will gradually soften in color over time. Please enjoy the blessings of nature.
