I would recommend searching this site under the headings on the left hand side. Many parents have discussed their experience with various Dr's and health professionals in this arena. However, many Dr's are quick to label ADD/ADHD and prescribe meds. If you don't want to put your son on meds there are many proven alternatives that can help improve focus. Diet can play a huge role (many great responses from Mindy and others on this topic, too).
I highly recommend an incredible book titled Adaptogens: Herbs for Strength, Stamina, and Stress Relief by Winston and Maimes. From the book "There is a category of herbs called adaptogens that help the human body adapt to stress, support normal metabolic processes, and restore balance. They increase the body's resistance to physical, biological, emotional, and environmental stressors and promote normal physiologic function".
The 10 most potent adaptogens on the earth, with the highest therapeutic properties available are now delievered in a fast acting oral spray, called Tunguska Mist.
Go to www.VitalHealth.TunguskaMist.com to learn more.
Many parents have had wonderful results using the Tunguska Mist Pure to help restore balance in their children and improve their focus. Teachers often comment that the student's grades go from C's/D's to A's/B's.
My husband and I have been taking adaptogens for a long time, and we're passionate about helping people reduce the damaging effects of stress and restore balance NATURALLY, without medications. Good luck and God Bless:)
