An herbaceous orchid from the Orchidaceae family, Dendrobium (Shi Hu) boasts a long history of use in China and is revered as one of the “Nine Immortal Herbs.” As recorded in the Shennong Ben Cao Jing, Dendrobium is sweet and neutral in nature, used to treat internal injuries, alleviate pain from obstructions, descend rebellious Qi, and tonify the five vital organs—combating wasting and strengthening Yin. Esteemed herbalists note that Dendrobium’s neutral and sweet properties allow it to enter the lung and spleen meridians harmoniously, supporting the body’s vital energy. When applied externally, it deeply moisturizes and repairs the skin barrier, effectively alleviating dryness and sensitivity.
