My son is 5 years old and he is contantly sick this year with strep or other cold viral infections. I took him to a homeopthic doctor and he told me to combine Callendula, Camomile, eucalyptus and salvia and brew the mixture overnight. Then I should dilute it with water and use it as gargling liquid for my son, as well as nose drops - Is this safe??? What else can you recommend.
