The spicy dish created by Gurpareet Bains contains oil that is said to produce “intoxicating” effects, the Daily Express reported.
The insomnia-fighting recipe contains nutmeg, a spice which contains a psychoactive substance.
The dish appears in the Indian chef’s latest cook book, “Indian Superspices”, a collection of recipes designed to fight everyday illnesses.
Bains says he can turn traditional Indian dishes into disease-fighting concoctions.
He says the lamb masala curry was created to help people combat the woes of sleep deprivation.
“Its ingredients have been used for millennia for their tranquilising properties,” Bains was quoted as saying.
Experts, however, recommend eating no more than half a nutmeg in any 24-hour period.
The Indian chef also said he recommends that no more than one portion of his curry should be eaten per day.
