Скачать или смотреть Harvesting the Latex from Lactuca Sativa (Garden Lettuce) with a Sponge

By the time I visited this farm all of the Wild Lettuce plants were beyond the harvesting stage. The plant I'm working on is Lactuca Sativa (cultivated lettuce) that has been allowed to go to seed for several years. I wish I had gotten a picture of it before I tore the leaves off. I don't usually harvest this type of lettuce, but it does create a fair amount lactucarium when left to its own devices. I first learned about its properties from my grandmother who kept a bed in the corner of her yard that she allowed to naturalize, she used it for tea. I found this to be as strong as my weakest wild lettuce plants, which isn't too shabby. In India they use Lactuca Sativa seeds as medicine, it's called Tukhme Kahu. I've linked to a study below that discusses the lactucarium in cultivated lettuce.

Study: Sesquiterpene Lactone Conjugates in Lactuca

This study shows the strength of sesquiterpene lactones in Lactuca Sativa during the rosette, bolting, flower, and seeded stage. Interestingly, it's a variety of garden lettuce. There is a table of the data in the upper right corner of page 5.
