TechWorld - helping you to feel better faster

February 5, 2013

Coughing, sneezing, stuffy nose, sore throat, fever ... sounds like a bad cold. Put on some chicken soup, drink plenty of fluids, get lots of rest and wait it out — in a week you'll feel better. Or, you could buy over-the-counter remedies to treat the above cold symptoms and you'll probably be well in just seven days. Wouldn't it be great to feel back to your normal self in only one day? With the help of a DrHealing ColdFluCare Kit from TechWorld Corporation Inc. in Milford, you could be. Now in its 14th year, TechWorld recently moved from Pennsylvania to Delaware where it is continuing research, development, manufacture and marketing of medical devices, OTC drugs and nutraceuticals.

One of TechWorld's founders, Dr. James Z. Liu, a physician specializing in prevention and epidemiology of infectious diseases, learned in medical school there are more than 200 viruses that can cause the common cold — and they all grow in the nose. One day when he came down with a cold, he used a NasalCare Nasal Cleanse Kit, now part of the ColdFluCare Kit, to do a deep nasal cleaning in the afternoon, evening and at bedtime. He reasoned that if he could cleanse the viruses out of his nose he could remove the cause of his cold. And it worked. The next day he felt fine.

His son Devin had a similar experience the day before he was to take the national ACT exam. The next morning he was symptom-free, and after the hours-long test Devin headed for tennis practice instead of crawling into bed.

Sound too good to be true? A study reported in the Journal of Infectious Diseases and Immunity in 2011 compared two groups of people suffering from a cold or the flu. One group was treated with the traditional standard of care while the other performed a three-times-a-day nasal cleansing with NasalCare Nasal Cleanse Kit under a physician's direction. After two days of treatment, the Nasal Cleanse group had significantly less severe symptoms than the comparison group.

Liu explained that cold viruses thrive at temperatures of around 91 degrees F., which is about the temperature of the human nose. It's impossible to tell which cold virus is causing an infection, and there are no antiviral drugs to treat a cold. A complete upper airway cleanse can remove the majority of viruses from nasal cavities and oropharynx. Physical removal in this manner does not harm the nasal cavities or any other parts of the body, Liu said. Although he describes it as "liquid surgery" for its efficacy, nasal cleansing is as simple as brushing your teeth, he said. You just need the right tool and to learn the correct, simple technique.  

The ingredients are a combination of sea salt, aloe vera, sodium bicarbonate (baking soda), sodium citrate and citric acid, a natural preservative. The product has no side effects. There's no risk of developing drug resistance or causing virus mutation. Nasal cleansing also has an anti-inflammatory effect because it also removes inflammatory mediators such as histamines, prostaglandins and leukotrienes that are contained in nasal mucus and cause nasal tissue damage.

Liu has been an inventor and an entrepreneur for 14 years after serving as a medical investigator in academics for more than 10 years. His business training was largely completed when he was senior project leader at Abbott Laboratories for six years. He was trained in medicine at Shandong University School of Preventive Medicine and further trained and received a doctor of philosophy degree in Human Nutrition from Penn State University in 1993. He has published 32 peer-reviewed medical research articles and received numerous medical research awards. He has authored 15 U.S. patents.

Liu declared a war against common cold on Oct. 28, 2011. He hopes that all members of the global village will be actively participating in the fight to win this special war. 

TechWorld also produces NasalCare brand Nasal Irrigation System for Children, DrHealing brand products such as AsthmaCare Kit and Spray, ColdFluCare Kit and Spray, and SoreThroatCare Kit and Spray. Additional products include a line of ONE-OK multivitamins and minerals. A new All-in-One OralCare Kit including liquid floss will be launched in 2013. 

TechWorld products are available in several retail drug stores. To order online, visit For more information, email or call 302-595-9307.



Is it cold or flu? Both a cold and the mild flu are viral infections of the nose, and the symptoms of the two are very similar. One major difference is that a cold affects the upper respiratory tract, and the severe flu attacks the lower respiratory system.  Generally, the flu is worse than a cold. The flu normally presents as muscle pain and a severe fever. The flu also poses a greater risk of worsening into pneumonia or bronchitis that can lead to hospitalizations.

Dr. Liu cautions that an effective antiviral drug should be used when needed (prescribed by a physician), especially if the virus is located in the lungs or other areas of the lower respiratory tract. The nasal cleanse is only for removing viruses from the upper respiratory and is unable to remove viruses in the lower respiratory tract. When you don't know which viruses cause your infection at the beginning, Dr. Liu recommends you should always perform a complete nasal cleanse as it has no harm and it can reduce the risk to spread viruses to others.
