In order to shine on the Oscars red carpet, Hollywood starlets need to prepare with top-notch trainers, expert stylists and the absolute best homeopathic product to fight the flu — Oscillococcinum! When celebs like Debra Messing and Felicity Huffman can’t afford to miss an appearance, they turn to the ultra-popular Oscillo, and with the winter sniffles spreading like wildfire, casts of hit shows like Grey’s Anatomy, Gossip Girl, Entourage and Ugly Betty pass around the FDA-regulated product on set. Not only A-listers can use Oscillo — it works for the not-so-famous too, and can be picked up from Whole Foods Market or CVS.
