Milk of the poppy is essentially the Westeros version of morphine. Maesters make it from crushed poppy flowers, and morphine and other opiate-based drugs are made from poppy plants. Indeed, the books' descriptions strongly suggest that the poppy is intended to be the real-world opium poppy (Papaver somniferum).
Poppy seed is an oilseed obtained from the opium poppy (Papaver somniferum).The tiny kidney-shaped seeds have been harvested from dried seed pods by various civilizations for thousands of years. The seeds are used, whole or ground, as an ingredient in many foods, and they are pressed to yield poppyseed oil.onversely, poppy straw can be a by-product of cultivation of poppy seeds. Compared to the seed pod and straw, the seeds contain very low levels of opiates. The seeds may be washed to obtain poppy tea but a large amount is needed, around 300-400g depending on the levels of opiates.
