Luohanguo is a fruit that we Westerners are hearing about because lately only because we have become rather obsessed with finding healthier sugar substitutes. However, the Chinese have had luohanguo in their "secret" arsenal as a natural sweetener and healing remedy for many centuries. Monk fruit, or lo han guo, is a small green melon native to southern China and named after the monks who first cultivated it centuries ago. The health benefits of the fruit have been well-known in Traditional Chinese Medicine (TCM) for decades, but its sweet little secret is finally making it into the wellness mainstream.
