Apparently spraying or irrigating the nasel passage with salt water provides similar effects. There are probably a number of things when spraysed up the nose would be helpfull, however from a product marketing standpoint I don't see ZICAM as being widely marketable.....not in the context of pills and tablets. Mad2healthcentral.com Salt water nasal rinse may prevent colds SAN FRANCISCO (Reuters)--Daily salt water 'irrigation' of the nasal passages may help protect against the common cold, researchers report. Nasal irrigation treatment was "effective" in reducing overall incidence of colds among practitioners, according to Dr. Richard Ravizza of Pennsylvania State University in University Park, Pennsylvania. Ravizza presented the findings recently at the 50th Scientific Assembly of the American Academy of Family Physicians, held in San Francisco. Ravizza told conference attendees that nasal irrigation has been a part of yoga health-oriented "cleaning rituals" for centuries. He explained that many practitioners use a small, narrow-spouted teapot-like utensil, called a "neti," to pour lightly-salted warm water into one of the nostrils. The head is then moved so that the water runs out. Adherents also make what Ravizza called "forceful exhalations" to expunge the remaining water, and further cleanse the nasal passages of residue. In their study, Ravizza and Penn State colleague Dr. John Fornadley divided 294 college students into one of three subgroups. One subgroup performed daily nasal irrigation, one took a daily placebo pill, and the third group was left untreated. All participants were asked to keep a "cold symptoms diary." The authors found that students who used the daily saline rinse experienced a significant reduction in the number of colds contracted compared with non-users. On average, those engaging in nasal irrigation had fewer colds over the study period, the authors say, compared with the placebo or untreated groups. Ravizza told Reuters Health that no one is quite sure how nasal irrigation might work to protect the nose against viral infection. "At a physical level, just cleaning it out, irrigating it, is probably helpful," he said. "At a molecular level, at a cellular level, I have no idea." Of course, forcing water up one's nose is not for everyone. But Ravizza noted that, after an initial week-long adjustment period, "50 percent of the subjects who formed the nasal irrigation group characterized (the procedure) as pleasant. Many said it was soothing, others said it was comforting." Of the remainder, 21 percent said they had "neutral" feelings regarding the procedure, while 29 percent found it uncomfortable. Ravizza said that most people who perform nasal irrigation require proper training. "The key thing is to have good instruction," he said. He suggested that those interested in trying out the technique contact a local yoga center, or an organization like the Himalayan Institute.
