Kosher-certified, lactose-free, sugar-free natural flu protection with Influenzinum*

Content: Mouth spray (30 ml)



Winter Tonic Plus is a remedy combining the flu vaccine strains of the current year with flu strains from years past and natural remedies which best protect against catching the flu. Winter Tonic Plus is taken

  • to increase and strengthen your body's natural defense against flu viruses,
  • to naturally protect against symptoms associated with the cold & flu, and
  • as a non-drowsy, chemical-free way to prepare yourself for the flu season.

Like the flu nosode Influenzinum, Winter Tonic Plus has been prepared for individuals and families who are looking to avert the flu holistically. Made in our natural pharmacy, it is free of mercury and other preservatives and comes in form of our lactose-free, sugar-free, kosher certified by KOF-K, and vegan mouth spray — ideal for consumers with dietary restrictions and dietary preferences. One dose is recommended once a week during the cold & flu season.

Combine Winter Tonic Plus with lactose-free, sugar-free, kosher, and vegan Thymuline to follow one of the most popular natural flu protection protocols started in France and now used throughout Europe, the U.S., and Canada. The protocol recommends one dose of a flu-vaccine-based remedy and one dose of Thymuline per week. Thymuline supports the Thymus gland, a key organ of the immune system, and is recommended during the cold & flu season as well as allergy season.

If a cold or flu commences, add Winter Balance II for lactose-free, sugar-free, kosher, and vegan acute cold & flu relief.


Spray 3 squirts under tongue once per week during the cold & flu season or year-round.  Allow liquid to remain in mouth for a few seconds before swallowing. 

Take 15 minutes before or after food or drinks.

Pure spray contains organic and kosher alcohol and is for adults and children 13 years of age or older. Follow the alternative method of administration below for children under 13 and to avoid alcohol:

Put 3 squirts in 1 ounce of warm, filtered water. Let sit in open air for 20 to 30 minutes for alcohol to evaporate. Take liquid in a clean mouth and keep in mouth for a few seconds.

In addition to being formulated anew every year to include the current year’s flu protection, Winter Tonic Plus is fortified with Krebs cycle acids which support efficient cellular respiration. The Krebs cycle or citric acid cycle converts nutrition to energy on a cellular level and is considered an important step in strengthening the body and preparing it for the flu season.

The Krebs cycle, or citric acid cycle, was discovered in the 1940s by Hans Krebs, a German physicist and biochemist. The Krebs cycle delineates the important chemical reactions necessary for cells to convert nutrients into energy. The basis of modern understanding about metabolism and energy is based upon the work of Hans Krebs, who received a Nobel Prize in 1953 for his discovery and definition of the citric acid cycle.

The Krebs cycle acids, alpha-ketoglutaric acid, pyruvic acid, citric acid, pantothenic acid, succinic acid, fumaric acid, and malic acid, are the major factors necessary for the Krebs cycle to complete the creation of energy on a cellular level.  These acids can be depleted or lacking as a result of stress, illness, muscle exhaustion, or genetic disorders. An insufficient amount of these acids causes the body to revert to less efficient methods of creating energy in the cells, creating lactic acid buildup, fatigue, and over-acidity in the body.
