To hell with Viagra. For problems of impotence and sterility, dancing in a Kakuungu mask (pictured) made from the finest wood, fiber, and hair can get the juices flowing. The largest of the initiation masks of the Suku and Yaka peoples of the Congo, it’s meant to ensure health and vigor. See your local diviner for details. But go prepared. Before prescribing the mask, she’ll make contact with the spiritual world, read a series of questions, and probably find out your long history of spiritual neglect or transgression; perhaps she’ll even discover that the moral corruption of the past is being revisited upon you. But not to worry—you’re in good hands. If she can’t address your problems, she’ll recommend a healer—or a visit to the National Museum of Health and Medicine. The exhibit “To Cure and Protect: Sickness and Health in African Art” presents more than 100 objects, including gourds, amulets, and divination tools, used in traditional healing in countries including Cameroon, Ghana, and Tanzania. It’s on view daily from 10 a.m. to 5:30 p.m. to Monday, Aug. 23, at the National Museum of Health and Medicine, 6825 16th St. NW. Free. (202) 782-2200. (Ayesha Morris)
