Friend is not currently on any prescribed meds but has been taking a couple of codeine for a few days for migraines which I suspect is something to do with it.
by chance we were discussing dandelion and burdock on another thread...this has beneficial effects on the system and provides a mild diuretic and laxative.
I've used senecot in the past (same reason, painkillers making me constipated). However it is not 'gentle relief' by any stretch of the imagination so make you're not planning on doing anything the following day and that you have soft tissue!
Funny you say that China, I haven't taken any yet because I'm training someone at work this week and would rather avoid any obvious disappearances. I'm hoping big bowls of bra flakes might fix it :)
