gypsywort

I discovered this plant in the garden last year.
Once I knew its name I couldn't dig it up as a weed...
It is spreading fast this year. Has anyone had any experience with it ? Is it dangerously invasive ?

 

If we're talking Lycopus Europaeus then no more so than other mints.

 

Thanks for replying
If it belongs to the mint family, I had better put a stop to it right away...
