I suspect the damage is done - you will have a sore tongue for a while till it heals, I'd guess. Think I'd be inclined to pop a Clarityn to see if it helps, but its probably a bit late for that - might be worth a try though, and if it does, continue to take them for a few days. Otherwise what about Bonjela or something? Or a trip to your GP?

Thankyou for your reply, I did telephone poison centre and ask their advice but they said Id have to eat reasonable qtys to be at any risk. After reading many websites regarding poisonous plants I was suprised at how poisonous this plant actually is. I always wear gloves until this incident which shows you how careful one has to be. I may try some Bonjela now thankyou.

I'm always hacking these back and digging them out, not wearing gloves, have never had a problem - but then I've never got it in my mouth, my hands are usually so disgustingly muddy and dirty in the garden its not an option till they're washed. I should imagine its just local irritation to the tissues of your tongue rather than any risk of poisoning you fatally with such a tiny amount, but if it doesn't clear within a day or so, I'd be inclined to visit my GP to get him to have a look. although having said that, it takes longer than a week to get an appointment at my doctors, lol!

Sorry about your tongue but thanks for the question as I didnt know about this. I am assuming its all Helenium Bamboo? must watch my step with mine.

Apparently, yes - I never realised, but then I always assume that everything in the garden is poisonous unless its a food plant. Didn't know the sap could be irritant, although it seems it doesn't irritate the skin (I've certainly had it on mine).

thanks Bamboo
