Indications

Expels intestinal parasitesStrengthens the Spleen and augments qiClears the heat of childhood nutritional impairmentSupports a depleted child through the expulsion

Childhood nutritional impairment with parasites, deficiency predominating. Parasites and long-standing malnourishment have exhausted the Spleen and Stomach, so an expulsion alone would take more from the child than the parasites do.

  • Classical childhood with parasites and marked weakness
  • A wasted child with a distended abdomen and no appetite
  • Restlessness, night sweating and irritability in
  • Dull eyes and poor vision in the classical description
  • Parasite patterns in a child too depleted for plain expulsion

PulseThin and weak

Modern Applications

AscariasisIntestinal parasitesFailure to thriveMalnutrition in childrenChronic diarrhoea

Common adjustments

  • Heat marked with irritability and constipation — keep Lu Hui 芦荟 within its 2–5 g limit rather than increasing it
  • Diarrhoea already present — reduce or omit Lu Hui 芦荟 — it is a strong purgative
  • Deficiency very marked — increase Ren Shen 人参 and Bai Zhu 白术 and delay the expulsion
  • Parasites cleared, weakness remaining — stop the parasiticides and continue with a Spleen formula such as Jian Pi Wan 健脾丸

Contraindications

Contraindicated in pregnancy — Lu Hui is a strong purgative traditionally prohibited in pregnancy, and Wu Yi is graded slightly toxic. Not for an acutely ill, feverish or dehydrated child, who needs medical care. Lu Hui is not used where there is already diarrhoea or a cold, weak digestion. Ye Ming Sha is an animal excrement and must come from a properly processed pharmaceutical source. Paediatric amounts are set by age and weight by a practitioner, the course is short, and a child who is not growing always needs a paediatric diagnosis rather than a herbal formula alone.

For licensed practitioners’ reference only — not a self-treatment guide.

Pregnancy

Contraindicated in pregnancy and while breastfeeding. Lu Hui is a strong anthraquinone purgative traditionally prohibited during pregnancy, and Wu Yi is graded slightly toxic with no established safety in pregnancy. This is a paediatric formula; a pregnant patient with suspected parasitic infection is managed by a physician, since antiparasitic drug choice and timing in pregnancy is a medical decision.
