Incidence of the common cold, flu and respiratory problems often increase at the onset of the fall season. The natural approaches to managing these conditions include providing herbs and nutritional support to strengthen immune functions, and help respiratory congestion, provide antioxidant action, and moderate nutritional imbalance.

Respiratory and Immunological support

• Piper longum (long pepper) has been used in traditional systems of medicine in the prevention and treatment of respiratory congestion and bronchial asthma
• Adathoda vasica has been traditionally included in preparations for the relief of cough, asthma and bronchitis. The component alkaloid, vasicine, has bronchodilating properties which helps to clear the air passages.
• Tylophora indica (asthmatica) This herb has been used traditionally in the management of bronchial asthma and respiratory problems
• Andrographis paniculata has been used in Nordic countries to provide relief from and to reduce the duration of symptoms of the common old and flu. This plant is traditionally used in the management of infections through strengthened immune functions. Current research on the active principles, the andrographolides, has validated their immunological effects
• Ocimum sanctum or Tulsi belongs to the class of adaptogens or bioprotectants, that help to enhance adaptability to changing weather conditions
• Glycyrrhiza glabra, licorice, helps to soothe the respiratory system. Glycyrrhiza glabra has four rather remarkable constituents: glycyrrhizin, glycyrrhetin, glucuronic acid and glycerrhizinic acid, which in combination act in a manner similar to steroidal hormones, in suppressing inflammation of mucous membranes

Antioxidants

• The shivering in the initial stages of flu is caused by compounds called pyrogens which act like free radicals and propogate extensively. Antioxidants not only alleviate these symptoms, but may also retard the replication of the flu virus
• Curcuma longa, (turmeric) and its yellow principles called curcuminoids are well recognized phenolic antioxidants which also have antibacterial and antiviral properties. Curcuminoids provide two-pronged ntioxidant activity: prevention of free radical formation and intervention to neutralize existing free radicals
• Green tea is yet another bioprotectant, which based on a reported study, can prevent the flu virus from entering the cells. In this study, Amandatine, a promising anti-flu drug, was required in up to 100 times higher concentration to match the antiviral potential of green tea catechins
• N-Acetyl Cysteine, a precursor of reduced glutathione, is proven to enhance immune system functions and offer protection against the influenza virus. In a six-month clinical study, subjects receiving 600 mg NAC twice daily, were less likely to develop influenza, as compared to controls receiving a placebo
• The trace element selenium, supplied in a bound form with the amino acid, methionine, (selenomethionine), is a highly bioavailable antioxidant which regenerates glutathione. Based on epidemiological studies there is a high positive correlation between body selenium levels, glutathione levels and the overall state of good health
• Zinc monomethionine, a highly bioavailable form of the essential trace element zinc is a valuable adjunct to antioxidants. Zinc is a key component of the enzymes that participate in antioxidant reactions and support the immune functions
• Hot Sip® is a formulation containing Adhatoda vasica, Alpinia galanga, Glycyrrhiza glabra, and Piper longum
• Alpinia galanga contains antiseptic constituents which exert antimicrobial action, primarily in the large intestine

Digestive functions support

• The fruits of Terminalia chebula, Terminalia belerica, and Emblica officinalis combined in equal proportions is known as Triphala. This formula and its individual ingredients are highly valued in Ayurveda, being compared to a "good manager of the house" in aiding digestion, nutrient absorption, and metabolism. Triphala can be particularly useful in alleviating indigestion, which is more likely to occur during autumn
• Ginger extract and Deglycyrrhizinated licorice extract (DGL) also help to promote digestive functions
• Probiotics (Lactospore®) and digestive enzymes (DigeZyme®) help to rectify impaired digestion and improve gastrointestinal functions
