The Viral Infection Fighter

Virafect is a formula based on herbs with years of traditional use for colds, flu, fever and viruses. When suffering from upper respiratory infections of a viral nature, reach forVirafect.

The ingredients in this formula - andrographis, wild indigo, Echinacea purpurea, holy basil, and thuja - are medicinal plants with years of traditional use behind them. Modern clinical and laboratory work confirms that they are especially effective for treating upper respiratory tract and viral infections. The anti-infective properties of each herb are improved by their synergistic dynamics.


Andrographis - With a long history of medicinal use in the Far East, andrographis is listed in the Pharmacopoeia of the People’s Republic of China, which enumerates its traditional use indications as influenza with fever, sore throat, acute or chronic cough, colitis, dysentery, and urinary tract infection.

In the light of repeated clinical trials herbalist Peter Holmes summarizes that andrographis “has emerged as one of China’s foremost immune stimulating anti-infective remedies for a large variety of bacterial, viral, and parasitic infections.”

Echoing the Pharmacopoeia of the People’s Republic of China, the extensively referenced WHO Monograph on andrographis points out that the following uses of this herb are supported by clinical trials: “Prophylaxis and symptomatic treatment of upper respiratory infections, such as the common cold and uncomplicated sinusitis; bronchitis and pharyngotonsillitis; lower urinary tract infections; and acute diarrhoea.”

A 1995 randomised, controlled clinical trial concluded that andrographis “has the capacity to significantly shorten the course/duration of the (common cold)”.

Wild indigo - According to the outstanding naturopathic physician, Dr. John Bastyr, wild indigo made the difference between a good antimicrobial formula and a great formula. Wild indigo complements and improves echinacea’s anti-infective properties.

Wild indigo is both antimicrobial and anticatarrhal. Herbalist David Hoffmann explains that it “is especially valuable for the treatment of infections and catarrh of the ear, nose, and throat. It may be used for laryngitis, tonsillitis, pharyngitis, and catarrhal infections of the nose and sinuses.”

Echinacea purpurea - Eclectic physicians relied on Echinacea for its antiseptic powers, including serious infections like sepsis and typhoid among its indications.

A 2007 meta-analysis that examined many clinical trials over several years concluded that this amazing herb does indeed reduce the likelihood of developing a cold by 58%. The duration of colds was furthermore reduced by 1.4 days in echinacea users. When taken alongside vitamin C, echinacea reduced cold incidence by 86%, according to one of 14 studies reviewed above. Herbalists agree that echinacea decreases the severity of cold symptoms like cough, headache, fever and nasal congestion.

Many references contraindicate use of echinacea in autoimmune and progressive systematic disease. Herbal authorities Berris Burgoyne and Kerry Bone explain that “from a rational perspectiveÉ Echinacea is positively indicated in a number of autoimmune diseases and is without adverse effects. While more research is needed to understand the role of Echinacea across a wider variety of autoimmune diseases, the theoretical concern expressed by some authorities in the 20th century that Echinacea was contraindicated for this class of disorder is looking to be exactly that: theoretical only”.

Holy basil - Revered highly in the Indian Ayurvedic tradition as a rasayana , holy basil is used for a host of conditions, including arthritis, asthma, bronchitis, the common cold, diabetes, fever, influenza, peptic ulcer and stress. Various studies have corroborated significant benefits for coughs; peptic ulcers as well as the inhibition of inflammatory COX-2 and LOX enzyme systems, to name just a few other uses.

Thuja - Thuja has antimicrobial and antiviral properties, and it is an alterative. A 2005 randomized, controlled clinical trial tested the efficacy of a combination of wild indigo, Echinacea pallida/purpurea root and thuja in the treatment of upper respiratory tract infections. Patients recovered from colds in approximately half the time. Herbalist David Hoffman furthermore remarks that thuja promotes expectoration in cases of bronchial catarrh.

Combination rationale

Echinacea is the infection fighter par excellence; its benefits escalate by combining it with the other herbs in this formula. Andrographis and holy basil are both anti-infective and have millennia-long history of use for colds, fever and influenza. Wild indigo, while anti-infective in its own right, also enchances the effect of the echinacea.
