hhmmm...that's interesting. I am a type 1 diabetic and take insulin. I have eaten lots of basil and it has never effected my blood sugar.
Often times herbs simply provide a quick fix. You cannot just take herbs and expect to get healthy. There are no quick fixes. You need to change your lifestyle, especially your diet. YOu know what, eating a raw diet, or nothing but apples for a few days may be hard. But it's nothing like having to take insulin and have diabetes. Absolutely nothing. YOu are incredibly, incredibly lucky that you caught this so early on. Now is the time. After you've been on insulin for a while the harder it will be to get off. It's your choice. This is the rest of your sons life. Think of what could happen if he had to live with this disease and take drugs forever. I hope you make the right choice. Good luck!
