The secret is in the mix of ingredients. The star ingredient of this recipe is of course the chamomile. The apigenin in it binds to the GABA receptors in the brain, to produce a mild, calming effect, eventually improving sleep quality over time. As for the whole milk, the tryptophan in it is directly involved in the production of serotonin and melatonin. The Greek yogurt too contains tryptophan while the honey causes a slight rise in insulin helping the amino acid enter the brain more easily. Finally, the cardamom has a long Ayurvedic history for inducing relaxation, adding to the ‘sweet dreams’ profile of this innovative recipe.
