Random Questions

1) Are prescription drug vials recyclable?

2) Is there any reason to bother thawing frozen berries being put into muffin batter?

3) Is there any way to disrupt the reproductive processes of ragweed?

By the way, I recently learned that eating certain foods can exacerbate allergic reactions to ragweed pollen. I sort of knew that both chamomile and echinacea were problematic for me. I am going to try avoiding cucumbers, summer squash, and melon as well and see if that helps.
