Why people make this tea
Nuts are among the most nutrient-dense foods we know of, and walnuts stand out from the crowd. Their famously brain-like shape turns out to be a pleasant coincidence — they really are exceptional brain food, rich in omega-3 fatty acids, protein, and an impressive range of vitamins and minerals including vitamins A, B-complex, C, and E. In Chinese food therapy, walnuts are considered a premier food for nourishing the kidneys, strengthening the lower back, calming lung-related wheezing, and supporting brain function. The whole family of nuts — from pistachios and almonds to cashews and pumpkin seeds — is valued for its unsaturated fatty acids that help manage cholesterol and protect cardiovascular health.
Pairing walnuts with hawthorn creates a tea that works on multiple levels: walnuts nourish from the inside while hawthorn is well-known for its circulation-supporting and digestive properties.
