Thank you, SHE magazine, for this lovely piece:

"SHE HELPS"

Q: Is there an easy way to boost my immune system?

A: We've just discovered the great new rejuvenating Firefly health drinks range (fireflytonics.com; 020 7052 9720) with herbal extracts to banish winter blues.

Made from a blend of blood oranges, manuka honey, ginger, thyme, rosemary, elderberry and cinnamon, Health Kick option should give your immune system the boost it needs!  Other drinks in the range are health-targeted too, such as De-tox for when you've over-indulged the night before; Chill Out to help you switch off, or Sharpen Up for when you need to focus your mind, say for an interview or presentation.
