Cistus Incanus, aka, Mediterranean rock rose, has been a blessing for many who are dealing with chronic illness or who need extra defense from viruses. Found in Italy, Greece, and Turkey, it possesses potent anti-inflammatory and immune-modulating benefits. Dr. Klinghardt, MD PhD, has found this herb particularly helpful in silencing the retroviral activity, a possible common denominator in chronic illness. Retroviruses, which make up the common cold and even things like HIV, represent small pieces of messenger RNA that are able to make copies of themselves using the host DNA through a process of revere transcription. This is one of the reasons why the commonly called HIV is extremely difficult to treat… The retroviruses evade the host immune system and use its own machinery to make copies of itself. Interestingly, approximately 8% human genome is made up of infectious retroviruses–most likely DNA fragments of old viruses leftover from human evolution. Since the dawn of man, these retroviruses have been relatively dormant. However, in the past 20 to 30 years, there have been many unnatural insults to our immune system- from our diets, antibiotics, toxic chemicals such as glyphosate, heavy metals, WIFI and electrosmog, and many other stressors have contributed to the reactivation of these retroviruses. While measuring retroviral activities is extremely difficult, retroviral activity can be detected using the Autonomic Response Technique (ART). One of the biggest discoveries that Dr. Klinghardt has had over the past several years, has been that there is a relationship between this retroviral activity, environmental toxicity, and chronic illnesses such as Lyme disease. Cistus Incanus, rich in polyphenolic compounds, as well as catechins, gallic acid, rutin, and other beneficial bioactive compounds, has the ability to not only reduce and silence retroviral activity but to treat previously difficult conditions such as Lyme disease. In essence, when the retroviral activity is properly tamed with the use of Cistus and other potent herbals, the activity of Lyme disease is also reduced. In this way, it is a potent immune modulator. Cistus is also an important agent to intelligently disrupt biofilm, the coating of cellular material that many viruses and bacteria live under. Another benefit is that it is easy on the gastric mucosa, while at the same time helping to reduce the bad bacteria and yeast living in the GI tract. We have found that not all types of Cistus are the same. For example, you can’t just buy it here in the United States, it has to be specially sourced from Sardinia.  It must be brewed in a special way and sweetened with a special form of Stevia to reach its maximal potential.
