Tang Piao Xiao (Mantis Egg Case): A Valuable Traditional Chinese Medicinal Material
Tang Piao Xiao is a well-known traditional medicinal substance used in Traditional Chinese Medicine (TCM) for centuries.
Although the name may sound unfamiliar to many people, it is actually the dried egg case, or ootheca, produced by praying mantises on trees, particularly mulberry trees. In traditional medicine, Tang Piao Xiao has long been regarded as a precious remedy due to its association with the treatment of various urinary and reproductive disorders.
Because of its rarity, unique origin, and historical medicinal importance, it has often been described as being « as valuable as gold » among traditional herbal practitioners.
What Is Tang Piao Xiao?
Tang Piao Xiao is the dried egg sac of certain species of praying mantis. Female mantises produce a protective foamy secretion that hardens into a capsule-like structure after being attached to branches, twigs, fences, rocks, or tree trunks. Inside this capsule are dozens or even hundreds of eggs that will eventually hatch into young mantises.
In traditional medicine, the egg case is collected before the eggs hatch. It is then cleaned, dried, and processed for medicinal use.
The medicinal material is commonly harvested from mantises that inhabit:
Mulberry trees
Fruit trees
Shrubs
Forest vegetation
Agricultural fields
The association with mulberry trees is particularly strong in East Asian medicine, which is why Tang Piao Xiao is often linked with the mulberry-growing regions where silkworm cultivation was historically common.
Physical Characteristics
Tang Piao Xiao typically appears as:
Oval or elongated in shape
Light brown to dark brown in color
Slightly curved
Lightweight
Hard but somewhat brittle when dried
The surface usually displays ridges and layered textures formed during the hardening process of the mantis secretion.
The size varies depending on the mantis species but generally ranges from several centimeters to over ten centimeters in length.
Historical Importance
Tang Piao Xiao has been recorded in traditional Chinese medical literature for many centuries.
Ancient physicians regarded it as a substance capable of strengthening certain bodily functions associated with:
Kidney energy
Urinary control
Reproductive health
Vital essence preservation
Because of these traditional beliefs, it became a frequently prescribed ingredient in classical herbal formulas.
In many historical texts, Tang Piao Xiao was considered particularly useful for conditions involving weakness, loss of control, and deficiency-related symptoms.
Traditional Medical Properties
Although often associated with male reproductive health, Tang Piao Xiao has also been used in women.
Traditional uses include support for:
Excessive vaginal discharge

Sleep disturbances
In such cases, it is usually combined with additional herbs that nourish the heart and calm the spirit according to TCM principles.
Collection and Preparation
The preparation of Tang Piao Xiao requires careful harvesting.
Collectors typically:
Harvest them before hatching occurs
Remove debris
Dry them thoroughly
Store them in a cool, dry location
Before medicinal use, the material may undergo further processing.

Dry roasting
Powdering
