Here's a glass of 'Barong Sex' in a modern jamu kiosk in Yogjakarta. It contains a duck egg, wine, galangal, and rice water. It's served with a free hard-boiled sweet (candy). Swigging this down is believed to increase the sexual stamina of men. Few male jamu customers use the traditional markets, which remain the haunt of women. Instead, men prefer to furtively frequent the more modern ‘high street’ kiosks for their doses of macho man jamu.
These kiosks, often also run by men, are chock-full of pre-packaged factory-made jamu promising weight gain, weight loss, reduced acne, fuller breasts, tighter vaginas, and help to quit smoking.
