Doctor: "I'm afraid not. We could dial down the dose even more, or even try stopping thearpy until he gets over this bout of side effects, but we'd have to start up again."
Client: "Is there an herb we could use? Something natural that wouldn't have the side effects?"
Doctor (after a pause to carefully consider his words): "Not that I'm aware of."
Me (inside my head): "We have a special name for 'natural herbs' that are effective and have fewer side effects than your current therapy. We call them 'drugs' and we would have already dispensed it to you."
