Why don't doctors offer something for AD HD other than psychotropic drugs? (Like herbals) ?

Shouldn't doctors offer safer things like herbals instead of psychotropics first? My children where on psychotropic drugs for AD HD. I took them off at one time but they went from excelling to failing. With no alternative I put them back on them. After a lot of research I recently put my children, on my own, on a combination of herbals. This is working well for my oldest but my youngest is still having trouble so I have ordered another herbal for him because he is very active. I hope it works for him. My point is that the herbals are working even though my youngest is still having trouble he is still getting A's and B's with the herbs with no side effects. The only side effects are possible allergy. I checked and cross checked the ingredients with his meds because there can be side effects with some herbs. But this option was never offered by my doctor. Maybe because I knew about adder-all and requested it when my son was having trouble, but shouldn't they have said try this first its safer? I would like to say that herbals are great but if you decide to try herbals too, research the ingredients and cross check them for interactions, they may be herbs but that does not mean they can't be harmful if abused or put in the wrong combination. Also don't expect them to work like magic. It is harder to get homework done but my kids I know are safer and healthier now. (I researched Attentive child, calm child by planetary, DMAE, Childrens DHA and causes of AD HD)
