Adzuki beans have long been used in traditional Japanese sweets, such as anko (sweet red bean paste), and are often enjoyed during celebrations and seasonal events. In Japanese culture, they’re believed to bring good luck and ward off evil spirits and illness, making them a symbolic and nourishing part of many rituals.

Interestingly, adzuki beans actually originate from China, where they have also been used in traditional Chinese medicine for centuries. In Yakuzen, adzuki beans are recognized not just for their taste and cultural significance, but for their powerful health benefits—especially when it comes to reducing water retention and supporting the body’s detox pathways.

They are classified as a neutral-natured food, meaning they are suitable for regular use. Their actions are linked to the heart and small intestine meridians, and they are known to gently promote urination, helping to relieve bloating, puffiness, and swelling caused by fluid retention.

Adzuki beans are also believed to eliminate toxins, making them helpful for clearing skin conditions such as pimples, rashes, or boils, particularly those related to heat and dampness. They are often used during the "Tsuyu" season (Japanese rainy season) to help the body stay light and balanced.
