Allergies - 19 year old son

Hello All,

My son is 19 years old and always had pollen and other allergies. He suffers a lot every year. Today he had a asthma attack at 4am. He and I talk about Liver Flush for years, now he has agreed to do it. Is there anything different he has to do considering his age?

He also eats a lot of processed foods and now he is reacting to some fruits and veggies. Strange how can one react to things they have eaten all their lives? What makes that happen?

Please help me help my son.

Thank you.
