I had an unexpected event last night/this morning and hope in the least I can help by sharing and if others can illuminate me, all the better.
I bought a popular herbal tea to use for bad chronic insomnia (Celestial Seasonings Sleepytime Extra, with Valerian.) The active ingredients are 600 mg of chamomile, 160 mg of tilia estrella, and 25 mg of valerian.
I made the tea double strong (2 bags in one 8 oz cup of water) because I have done that before with other teas containing similar ingredients with no ill effect.
So here's the nasty surprise- the tea began to take effect, and then I was stricken by muscle pain all over my body- it hurt very very badly. Then it occured to me the chamomile (a muscle toner) must have made lactic acid come out of my muscles. I thought my Epsom Salt baths were leaching lactic acid out of my tissues but um, I guess not. I laid awake in wracking pain for a few hours before I gave in and took 2 Aleve.
I felt fine when I got up later (uh, much later) but I feel a bit dumb for learning the hard way to not go hardcore with herbal tea.
If anyone else has had this happen, please share....I will Google later to find out how NOT to repeat this incident. But firsthand stories would be more helpful. Thanks for reading.
