Natural Astringent Herb from Praying Mantis Egg-Case

Praying Mantis Egg-case (Sang Piao Xiao)

Overview:
Sang Piao Xiao, known as the Praying Mantis Egg-case, is a traditional Chinese medicinal substance derived from the ootheca (egg case) of various praying mantis species, primarily Tenodera sinensis or Statilia maculata. In Traditional Chinese Medicine (TCM), it is prized for its ability to stabilize the essence, tonify kidney yang, and support bladder function, especially in cases of urinary or reproductive weakness.

Botanical/Zoological Characteristics:
The egg-case of the praying mantis is a light brown, foam-like capsule that houses the mantis eggs. It is typically harvested in the autumn or early winter, cleaned, and dried for medicinal use. It has been recorded in classic Chinese pharmacopeias for centuries as a tonic to restore balance in the urinary and reproductive systems.

Traditional Uses in TCM:

• Stabilizes the kidney and secures essence: Commonly used to treat spermatorrhea (involuntary semen discharge), nocturnal emissions, and frequent urination due to kidney deficiency.

• Supports bladder control: Beneficial for enuresis (bedwetting), incontinence, and urinary dribbling, especially in children or elderly individuals.

• Improves mental focus and emotional stability: Often included in formulas that calm the mind and support cognitive functions associated with kidney-heart disharmony.

Pharmacological Properties:
Modern studies suggest Sang Piao Xiao may contain proteins and amino acids beneficial to the urinary and reproductive systems, and it is believed to modulate hormonal activity and support urogenital function. It has mild astringent, tonifying, and neuroprotective effects when properly prepared.

Preparation and Dosage:
Sang Piao Xiao is commonly used in decoctions, powdered formulas, or pill form. It is often combined with other kidney-tonifying herbs such as Yuan Zhi, Long Gu, and Fu Shen to enhance its stabilizing effects. A typical dosage ranges from 6–12 grams, depending on the condition and the individual’s constitution.

Precautions:

• Should not be used in cases of excess heat or yin deficiency with fire signs.

• Best used under the guidance of a qualified TCM practitioner, especially when treating chronic or complex urological conditions.

• Ensure the egg-case is properly sourced and processed to avoid contaminants or allergens.
