Isotoma Axillaris "Blue Star" WARNING - Sap is an "irritant"!!!

For the first time this year I have discovered the beautiful Isotoma Axillaris "Blue Star" which has flourished in our new sunny garden. However, having read advice that deadheading will prolong flowering - even though it has flourished, I decided to deadhead the plant 2 days ago. I was wearing surgical latex-free gloves to protect my hands due to rose scratches the previous day, and proceeded. I noticed that there was a milky-white sap where I removed the dead flowers & a certain "odour" from the sap, but thought no more about it.  However, at one point I had an itchy eyelid, so used the back of my knuckle to ease it (as I have often done before). Immediately I had terrible stinging in the eye, inability to open in & a temporary blindness with shock at something happening so quickly. I immediately removed my gloves, washed my hands carefully - thinking it was maybe the gloves (although this had never happened before), and then thoroughly doused me eye for more than 5 minutes with cool water. Eventually the stinging subsided & I was able to open my eye, but it was very bloodshot & tender, but my vision returned. Can I highlight this issue to other gardeners. I notice that your article on Isotoma Axillaris mentions that the plant is not poisonous to animals, however, there is no mention of the Sap being an Irritant. I later researched on the internet & discovered that on the Australian National Herborium website there is a warning IN RED, that the sap "can cause severe irritation to skin and temporary blindness if inadvertant contact is made with the eyes, and has to be reported as poisonous to stock". Also, later in the article that "Propagation from firm cuttings is also possible, (IN RED) but it is recommended that gloves are worn to avoid reactions to the sap". 

I just feel that as nothing seems to have been flagged about this in the UK, I should draw other gardeners' attention to this potentially dangerous issue - particularly if they garden in an area which does not have an immediate source of clean running water.

    Gosh, I've grown it on and off for years and didn't know that, but I don't deadhead it.

    Odd how your eye becomes itchy and needs a rub in these situations like picking chillies or dicing them for cooking. Dabbing the eye with a paper towel soaked in milk is one cure involving chillies but I do not know if it would help with your problem.
