- Distended abdomen with thin limbs
- Irritability, restless sleep and grinding of teeth
- Sallow complexion with dull hair and eyes
Health Categories
Modern Applications
Common adjustments
- Marked heat with irritability and thirst — increase Huang Lian 黄连 slightly — in a child this is a practitioner's decision
- Diarrhoea predominant — increase Rou Dou Kou 肉豆蔻 within its 3–10 g limit
- Deficiency predominant, parasites treated already — drop the parasiticides and use a Spleen formula such as Jian Pi Wan 健脾丸
- Food accumulation predominant — increase Shen Qu 神曲 and Mai Ya 麦芽
Contraindications
Not for a child who is acutely ill, feverish or dehydrated — that needs medical care. Contraindicated in pregnancy. Shi Jun Zi must be kept within its limit and is not taken with hot tea, a combination classically and clinically associated with hiccups, vomiting and dizziness; Bing Lang and Rou Dou Kou are both dose-limited, and Rou Dou Kou is toxic in overdose. Paediatric dosing is by weight and age and is set by a practitioner. Failure to thrive is never treated as a herbal problem alone: it requires a paediatric diagnosis, because coeliac disease, chronic infection and other causes look similar.
For licensed practitioners’ reference only — not a self-treatment guide.
Pregnancy
Contraindicated in pregnancy. Bing Lang drives qi strongly downward and is traditionally prohibited in pregnancy, and neither Shi Jun Zi nor Rou Dou Kou has established safety at therapeutic doses during pregnancy. This is a paediatric formula; a pregnant patient with a suspected parasitic infection needs a physician, since the choice and timing of antiparasitic drugs in pregnancy is a medical decision.
