Lipeao, a delicate climbing fern native to Thailand, threads together folk wisdom, rural livelihoods, and growing scientific inquiry. In northern and southern communities alike, this plant—known by many regional names such as Kud Khreu, Kud Ngaod Ngaed, and Leh Phao—embodies a living link between age-old healing practices and contemporary research. As Thai health advocates push for evidence-based natural remedies, Lipeao’s reputation is being reexamined through a modern lens while remaining deeply rooted in local culture.

From the leafy forests of northern Thailand to the backyard gardens of the south, the lacy climbing fern known as Lipeao (ลิเภา), or Lygodium polystachyum Wall. ex T.Moore, weaves a distinctive presence through local culture, traditional healing, and rural livelihoods. Revered under many regional names such as Kud Khreu, Kud Gong, Kud Ngaod Ngaed, Kud Pae, Kud Yong, or Pak Teen Tokto in the north, and Leh Phao, Lipeao Yong, or Yaa Yai Phao in the south, this ancient fern connects the tapestry of Thai herbal wisdom with modern scientific inquiry. Today, as a new generation advocates for evidence-based natural health, interest in Lipeao’s medicinal reputation is being reawakened—and scrutinized—for its healing promise and scientific validity.

Across rural Thailand, Cha-em Thai (Albizia myriophylla Benth.) remains a familiar healer in homes and villages. Locally known as ชะเอมป่า, ตาลอ้อย, ส้มป่อยหวาน, and อ้อยช้าง, this climbing legume has long served in simple home remedies. As interest in ethnomedicine grows, researchers are revisiting Cha-em Thai to see how traditional knowledge aligns with modern science and how the plant can be used safely today.

Traditionally, Cha-em Thai appears both as a standalone remedy and as a key ingredient in classic polyherbal blends known in Thai medicine as the ten roots. Decoctions from the wood, bark, or stems have addressed fever, sore throat, mouth ulcers, and general inflammation. The plant’s wide distribution—from northern to southern Thailand—reflects regionally diverse healing practices, where local names and preparations vary and enrich the country’s medical heritage. In Thai households, Cha-em Thai supports convalescence and digestion, and is often combined with other herbs to bolster wellbeing.

Across rural Thailand, Cha-em Thai – known to botanists as Albizia myriophylla Benth. – occupies a unique place in the landscape and in traditional healthcare. Locally called by many names like ชะเอมป่า (Central Thailand), ตาลอ้อย (Trat), ส้มป่อยหวาน (Northern Thailand), or อ้อยช้าง (Songkhla and Narathiwat), this woody climbing plant from the Fabaceae family has been utilized for generations as a key ingredient in home remedies for a range of ailments. As wellness-seekers look back to the roots of ethnomedicine, interest in Cha-em Thai is blossoming anew. But does modern research support its venerated role in Thai healing tradition? And how can this ancient botanical be used safely today?
