If I have a cold coming on I take 21 capsules of olive leaf fresh that has been sundried and ground and put in caps.
Not for your children this much.
I take 4 caps each day. I might suggest one cap a day for them and you it should be 4.
Olive leaf tea would be great for your children with some honey added. Try a small amount. I believe that olive leaf is almost as important as black seed and honey.
Read and do some research and let me know what you think.
God bless you oh one who loves her children so much.
