The West Asian crowfoot, or Selaginella doederleinii, is a species of fern originally found in Asia. This species is also known by the names Shi Shang Bai or Lycopodioides doederleinii. It has a distinctive green colour and produces small, hairy to the touch leaves. It grows mainly in tropical and subtropical areas of Japan, Korea and China and has a preference for moist shady environments. It is not demanding to grow, but prefers moderate moisture and acidic soils.

Its medicinal properties have been used by traditional Chinese medicine and it is now used in modern pharmaceutical products. In China, West Asian crowfoot is traditionally used as a diuretic and to treat kidney and urinary tract diseases. It is also used in the treatment of wounds and skin problems, as well as to reduce fever or as an anti-infective. Some studies suggest that it has antioxidant and anti-inflammatory effects. Its extracts are often found in a wide range of products, including teas, syrups, tablets or ointments. It is also included in some cosmetic products for its purported antioxidant properties. Despite its widespread use, it is important to consult a professional before taking it, as it may have side effects or interact with other medications.
