China Press reported that a handful of Indonesian maids practised witchcraft by contaminating meals and drinks with their menstrual blood and urine, done in the hope of building a closer rapport with their employers.

They believed that their ties with their employers would be enhanced once their bosses consumed the contaminated drinks, especially those mixed with their menstrual blood.

Religious scholar Wang Chen Fa said such a practice was common in Indonesia as it was deemed "powerful" and harmless to the health.

"In ancient China, the menstrual blood and urine of female virgins were mixed with other liquid as medication," he was quoted as saying.
