Should be fine. Eucalyptus and neem are native to their areas I believe. For your son pro biotics and emergen c. Not trying to tell you how to parent or nothing but being sick sucks. I take 4 to 8 probiotics pills then 2 to 5 emergen c packets in a small cup of water. That much beneficial bacteria and vitamins usually knocks anything bad and foreign out of your system. I think the Eucalyptus will be fine though.
