Interesting, Jess - as the immune system is very much your speciality, it's good to hear the real scientific background, because it helps me to form a balanced picture of what helps and what doesn't!
Thinking of herbal remedies, I agree that some may be, and some are, effective. But, for example, St John's Wort, which is a very effective anti depressant, can have a very detrimental effect on some pharmaceutical drugs - Tamoxifen, for example, and statins, reducing their effectiveness. So, like everything else, the message is to approach with caution.
