We had a large thread about that recently actually. I resolved to find some for my garden since it apparently grows easily, but then never followed up on it.
Is your kid watching the cooking channel late into the night? Have they been cooking up delicious curries? Are you getting a large bill from Penzey's Spices every month? It could be that they're actually a dangerous drug addict.
This is a wrong figure. My friend went through the draft of that piece and told the journalist it was a typo (I think the correct figure is closer to 30) and that he should write "several" to play it safe. He obviously decided that 300 sounded better. It's a great piece, but it's still something written by a journalist, not a scientist and it's still not a peer reviewed article.
lol, I thought it was a joke. That's probably something I would say flippantly to a journalist. Around 30 species of psychoactive ginger is still pretty amazing, actually.
