Hello group,

I wounder if I could ask for some ideas or advice.

Would any of the readers known the answer to this.

I am researching two chemicals, that if digested on their own are quite
harmless, yet if eaten with-in say 24 hrs of each our will become toxic
or even lethal.
The above may sound a little strange to say the least, but rest assured
I deal with toxins everyday.

Any help or advice would greatly be received, please feel free to use
email (remove spam filter first).

Thanks in advance

John
