What is a natural way to calm down adhd in a teenager?

Depends: Diet changes and allergy treatment if there are behavioral problems. Correct learning problems if focus and concentration are the problem.

Medication: Unfortunately, if your child has adhd, natural treatments are not shown to be effective. Reducing sugar and caffeine are always a good idea, but only medication has been shown to be significantly helpful.

Natural Remedies: Research shows benefit of aerobic exercise, diet (Earl Mindell's Vitamin Bible), and mental conditioning. You can train your brain to increase your ability to concentrate. Focus on pre-frontal cortex and consider exercises that work attention, mental flexibility, concentration, and impulse control.
