Yup, think so, somehow. it’s from medieval Latin. Linnaeus got it from there I think. Impatiens noli-tangere also used to be noli-me-tangere. Don’t me touch doesn’t roll,
I’ll have to look it up, though. And since all my books are in boxes in another place, I currently can’t look into my copy of Genaust, dammit.
That video might be produced by Attenborough, but he’s not narrating.

Touch-me-not is more of a “Oh crap I am out in the sticks and I just fell into some poison ivy, oh look, jewelweed”. Probably a combination of mechanical action of crushing the leaves with the aloe like sap on the skin, it helps.
GAHHHH The roots on dock are freaking evil. Ok, maybe a counter attack with poison ivy is on order.
Scientific literature speculates also about the role of saponins.
I think that the effect on nettle stings is more cooling and soothing than anything. Nettle injects a histamine under the skin while poison ivy coats the skin in urishiol, an irritating oil. The compounds in touch-me-nots actually break down the oil and disperse it assuming it hasn’t already penetrated the skin. I’ve never heard of dock being used for urushiol, but I’m intrigued now.
They’ve really nailed the time-lapsed tracking shots, haven’t they.
I’ll buy it. It has been years since I have tasted any, but I do recall it having that slightly soapy twang. I briefly looked into the chemistry a bit further, and plenty of potentially interesting compounds, Jewelweed Uses, Benefits & Dosage - Drugs.com Herbal Database
Like plants do, in general.
Fun fact: as an undergraduate, I looked at Busy Lizzies and dug out some figures. In the US alone, more than 250 mio $ were made each year from one cultivar alone (the ubiquitous New Guinea-hybrid).
