Children's Herbal Paste (Gao Fang) in TCM: Contraindications and Guidelines

Herbal paste (gao fang) is a winter tonic tailored to individual needs, gaining popularity for its ability to address specific health conditions. However, experts caution that its use in children requires careful attention to contraindications.

Children's organs are delicate, particularly the lungs, spleen, and kidneys. Pediatric herbal pastes are designed to address these inherent weaknesses and balance yin and yang based on the child's constitution. They can be beneficial for children with recurrent colds or asthma, helping to improve constitution, enhance anti-allergic capacity, strengthen lung qi, and prevent asthma attacks.

Contraindication: Children should be at least 4 years old before taking herbal paste. During the course, avoid raw, cold, greasy, spicy, hard-to-digest, and strongly irritating foods, as they hinder spleen and stomach function and reduce absorption. Additionally, avoid strong tea and coffee.

Three types of deficiency in children are identified:

Experts emphasize that herbal paste is targeted therapy—only children with weak constitutions or certain chronic conditions should take it. If there is no deficiency, do not supplement.

Contraindication: For children with chronic asthma, the paste may include ginseng or gecko; in such cases, avoid radish. If the paste contains polygonum multiflorum, avoid pork, sheep blood, and iron supplements, and do not take with milk (due to calcium, phosphorus, iron reacting with organic compounds in the tonic).

Children's herbal paste differs from adults'—they are in a state of 'tender yin and tender yang' and should not be heavily supplemented. Avoid warm kidney-yang tonics to prevent precocious puberty. The approach is gentle regulation, using mild tonics like codonopsis, pseudostellaria, and atractylodes, with minimal greasy or stomach-irritating herbs. Adding digestive aids like tangerine peel or finger citron ensures the tonic is both nourishing and harmonious.

The paste is typically taken from the winter solstice for 2–3 months. For best results, continue for at least three consecutive years. In the first week, give one dose daily on an empty stomach; after one week, increase to two doses (morning and evening) on an empty stomach.

Contraindication: If the child experiences dry mouth or constipation, halve the dose or extend the interval. Stop during fever, cold, acute diarrhea, vomiting, or asthma attacks, and resume only after recovery.
