Lucy does not care a whit whether you use blue or black ink, but her eyes aren't what they used to be, so she requests that you write legibly and large. Lucy regrets that she cannot respond individually, but she loves hearing from you.
Herbal products are chemicals.
They can have side effects and can interact with other herbals or conventional medications. Since herbal products are not regulated by the FDA, it is hard to know their strength and purity. Keeping these cautions in mind, it is clear that St. John's Wort does seem to offer some benefit for mild depression, but not for more serious depressions. Don't combine with other antidepressants. Use as directed on the label.
