Parents struggling to get toddlers to eat may find hope in a new study suggesting that certain traditional Chinese herbal medicines can improve appetite and weight gain in infants with anorexia, a condition marked by persistent food refusal in early childhood.
The comprehensive analysis, published in Frontiers in Pharmacology, reviewed 141 clinical trials involving nearly 17,000 children and examined 49 different commercial Chinese polyherbal preparations. Researchers used a statistical technique called Bayesian network meta-analysis to compare these remedies against conventional treatments and against one another.
Infantile anorexia typically appears before the age of three, often between nine and eighteen months. It is not the same as the eating disorder seen in teenagers and adults, but rather a functional feeding problem in which infants show little interest in food and fail to gain weight appropriately. Left unaddressed, it can lead to malnutrition, weakened immunity and delayed development.
The study found that a preparation called Huaji Oral Solution was most effective at improving overall clinical response, with children showing markedly better appetite and food intake compared with those on standard treatment. Another remedy, Erpixing Granules, stood out for helping children gain weight, while Jianbaoling Granules proved most useful for raising haemoglobin levels, an important marker of nutritional health.
Researchers noted that these herbal preparations appeared to work through several mechanisms, including stimulating digestive enzymes, regulating gut bacteria and influencing hormones linked to hunger. Encouragingly, side effects were generally mild, with occasional nausea, rashes or minor stomach upset reported, and no serious adverse reactions recorded across the trials.
The authors were keen to stress that the findings, while promising, come from studies conducted entirely in China, using formulations developed within traditional Chinese medicine practice. This means the results may not translate directly to children from different backgrounds or dietary cultures elsewhere in the world.
There were also some methodological caveats. Many of the trials lacked blinding or clear reporting of how participants were allocated to treatment groups, which can inflate perceived benefits. The researchers also flagged evidence of publication bias, meaning studies with positive results were more likely to have been published than those with disappointing outcomes.
Even so, the scale of the analysis, spanning three decades of research, offers useful guidance for clinicians considering alternatives to conventional appetite stimulants. The authors suggest that different remedies might suit different needs, with some better for short term appetite loss and others more appropriate for longer term nutritional recovery.
For families dealing with a persistently poor eater, the findings add to a growing body of evidence that traditional remedies deserve closer scientific scrutiny. The researchers say larger, higher quality trials are still needed before firm clinical recommendations can be made.
