Whatever your problem—asthma, no cash, fickle lover, trouble with the law—the Santeria superstore Casa de las Velas (New York's oldest existing botanica, established in 1921) has got a candle to cure it. And if a wick won't do the trick, the emporium's shelves are also packed with helpful herbs, charms, incense, saintly icons and bath preparations. It's one of the last remaining botanicas on fast-gentrifying 116th Street, and the store clerks are friendly, happily “blessing” your purchase for extra potency. But you risk a frosty glare and a finger-wagging “no” if you pull out a camera to snap the grimacing deities that hang from the ceiling.
