Truffles grow underground in association with the roots of certain trees, such as oak and hazelnut. Their unique aroma and flavor make them sought after by chefs and food enthusiasts. In traditional Chinese medicine, “芝” can also refer to various medicinal fungi, such as Reishi (灵芝). These fungi are believed to have health benefits, including boosting the immune system and promoting longevity. They are often used in herbal remedies and supplements, highlighting their importance in both culinary and medicinal contexts.
