Allergens can produce sensory, neurological, and behavioral changes, especially in children diagnosed with autism and/or ADHD. Certain Traditional Chinese Medicines may reduce allergic sensitivity/inflammation and alleviate autism/ADHD like behavioral symptoms. This is a retrospective case series on two patients with allergies, gastrointestinal issues and Autism/Autismlike who had improved behaviors and allergies after a Traditional Chinese Medicine (TCM) regimen. Two patients with autism-ADHD/autism-ADHD-like behaviors and severe allergies were treated using TCM to reduce their allergies and improve their behavior. These effects were achieved when the correct concentrations and doses of a series of TCM teas and treatments were reached. TCM appeared to be safe and well tolerated. TCM significantly improved the behaviors and allergies of both patients, therefore TCM may be a potential remedy for sensory issues, neurological problems and behavioral changes associated with allergies.
