– Thats a wonderful identification…! I have seen this species several times in Delhi, and ignored it assuming it to be Argemone mexicana.

– It is valuable herb in Traditional Healing. When ever you feel depressed (I am sure that this word is not present in your dictionary) collect the roots and keep it in palm for time being. It will help refreshing your mind/ mood.       

    Both yellow and white types are raised in Badi by the Traditional Healers using it as medicine. Many times you can find its “cultivation” in tribal areas for the greedy traders. It is adulterated with Mustard oil and it results in Dropsy as we read about such cases in newspapers time to time.

    Just to add Dropsy caused by Argemone seeds can be treated with the help of other parts of same plant.
Here is video link showing Argemone raised in Badi for use as medicine.

Argemone ochroleuca from Ismailabad(Haryana).. : 6 posts by 4 authors. Attachments (10)
Here am attaching images of Argemone ochroleuca (Papaveraceae) shot from Northern Haryana in April 2019. Its not much common as Argemone maxicana in this area.. We can distinguish it from latter by small height, pale yellow flowers and deeply dissected stigma…!!!

wonderful pictures, thanks. have the seedpods matured by now? if they are and you can get them, would love to see the seeds, close up. second question: do these grow as weeds also, in the mustard fields, like the other argemone?
