Herbs for chickens, part four: garlic, oregano and treatment claims
Garlic and oregano attract strong claims online. Research on a particular preparation may be interesting, but it does not establish that an unmeasured scoop of kitchen herbs treats a sick flock.
Separate food from medicine
An extract, essential oil and dried leaf can have very different concentrations. Findings in one type of poultry or under controlled conditions should not be converted directly into a home dose. More is not necessarily safer or more effective.
Do not replace diagnosis
If birds have respiratory signs, diarrhoea, poor growth or suspected parasites, investigate the cause with appropriate veterinary help. Herbs cannot reliably establish or solve the diagnosis. Keep drinking water clean and avoid adding products that reduce intake.
Make honest product decisions
Before launching a herb range, define the intended nonmedical use, ingredient quality, suitable birds and directions supported by evidence. Check current Australian rules relevant to the claims. Do not rely on another seller's label as proof.
Next step: enjoy garden and enrichment content while keeping treatment claims out of casual recipes. Customers should be able to trust both what we recommend and the limits we explain.
