NaturHeals - Wild Weeds 10 - Satyanashi – Argemone Mexicana – Mexican Prickly Poppy


Ask any farmer and he will tell you what nuisance weeds are. Weeds can grow anywhere, including on farmlands, and ruin the growth of crops. Weeds can cause major losses in the agricultural sector. But did you know that it is not possible to dismiss all the weeds as a nuisance or dangerous? This is because, in reality, there are some weeds that come with numerous health benefits. Satyanashi is one of them.

An invasive weed found all around the world, Satyanashi is the Indian name for Argemone Mexicana. The meaning of Satyanashi is devastating, and it seems like an unfitting name for a weed that is used as a medicine. However, Satyanashi is so-called because its seeds are toxic for human and animal health. The seeds of Satyanashi resemble that of mustard seeds and if its oil is diluted with mustard oil, it can lead to a serious illness (even fatal) called epidemic dropsy. Still, traditional medicine has used this plant to cure several health issues for a long time

Agremone Mexicana's allelopathic effect is extremely harmful to seedlings awaiting germination, especially for wheat, mustard, fenugreek, sorghum, finger millet, tomato, and cucumber important crops in India. The allelochemical cinnamic and benzoic acids inhibit germination & seedling vigour. Hence the name Satyanashi in India. Here you will find all the information about Satyanashi, a toxic but healing weed.

Planting and Harvesting

Planting And Harvesting

Planting and caring for Satyanashi is quite easy. You can directly sow the seeds in the land, as there is no need to transplant them. In fact, it is best not to transplant them, as the saplings are delicate and can easily break. The best time to sow the seeds of Satyanashi is 5-7 weeks after early spring when the temperature is 13o-16oC. The seeds should be sown at the spacing of 8 to 36 inches. After planting, the seeds start germinating in 2 weeks. Yellow flowers start appearing mid-summer to early autumn.

Ensure that the seeds receive full sunlight to germinate faster. As it is a weed, the Satyanashi plant can grow uncontrollably. To prevent this, it is best to get the poppies deadheaded before the seeds are set.

The plant is ready for harvest when it reaches the height of 24 to 36 inches. It is extremely crucial to wear gloves while harvesting, as the prickles, can cause harm. Once harvested, the leaves can be used fresh or dried to be used later.
