Wild Lettuce, Prickly Lettuce (Lactuca serriola)



Wild Lettuce


Wild Lettuce (Lactuca serriola) is the first to my mind when I think of pain. When there’s any pain, I think of easing it first, then addressing the cause, which usually means using another herb, but that’s just me…a wimp.

This prickly, unfriendly looking customer is around for longer each year, as the climate changes. Thats a good thing in my books (not climate change, but more Lactuca!).

As with a few of the herbs we have in Australia, ours isn’t the Wild Lettuce of the northern hemisphere, thats Lactuca virosa. There isn’t a lot of difference for our uses. The real difference comes when it’s time to harvest. L. virosa has more of its white sap in the stems, so it’s easier to harvest mechanically. L. serriola has the sap distributed throughout its leaves and veins, making it too sticky to harvest by machine.

It’s easy to identify, even amongst the other thistles that often grow around it, the flat leaves are held upright and along their central spine is a row of prickles that give it it’s other common name ‘Prickly Lettuce’. Like many other plants of this type, it has a bright yellow flower.


Some nasty looking prickles!

Like most other thistles, its leaves and stems contain a bitter, white sap. This is where all the goodness is. Bitters stimulate a lot of processes throughout the body, not the least being the secretion of gastric fluids to help digestion, giving energy and fire to sluggish conditions.

The most interesting component of the sap is a chemical that emulates opiates, without their addictive side effects.There is some division about the effectiveness of it in this species, but personal experimentation has found that the tincture of it is quite effective for minor aches and pain.

American herbalist, Matthew Wood, recommends using Wild Lettuce as a remedy for negative thinking, for the type of person who sits and thinks the worst before it happens, who are robbed of motivation by this kind of thinking.

I can see this in its physical form, its ‘signature’. The leaves are upright and the plant leads the eye to its bright yellow flower, but to get there, you need to get past lots of prickles and a very vertical form. just the kind of prickles in life and hard climb that the Wild Lettuce type of person needs motivation to overcome. The taste is bitter, something that many folks shy away from – another test to overcome before realising that life isn’t all struggle, but that many struggles do need overcoming in order to experience joy.
