The controversial history of high-dose vitamin C in cancer treatment
Utilizing high doses of vitamin C as a cancer therapy is no exception to this controversy. Nearly 60 years ago Toronto physician William McCormick observed that cancer patients often presented with severely low levels of vitamin C in their blood and featured scurvy-like symptoms, leading him to postulate that vitamin C might protect against cancer by increasing collagen synthesis. In 1972, extending this theory, Ewan Cameron, a Scottish surgeon, hypothesized that ascorbate could suppress cancer development by inhibiting hyaluronidase, which otherwise weakens the extracellular matrix and enables cancer to metastasize. He began treating terminally ill cancer patients and published a case report of 50 patients in which some of the treated patients benefited from high dose vitamin C.
So why did the Pauling and Mayo Clinic trials have different results? There are at least two crucial differences. First, the Mayo Clinic trials abruptly stopped the ascorbate administration, switching to traditional chemotherapy, when the patient developed signs of tumor progression. Thus, the overall median time of vitamin C treatment under the Mayo Clinic trials was only 2.5 months, while the Pauling and Cameron trials treated patients for the duration of the entire study period or as long as 12 years. Secondly, the Mayo Clinic trials administered 10 g of daily ascorbate to patients only orally, while the Cameron and Pauling trials administered their vitamin C both orally and intravenously. This difference in the two dosage routes proved highly consequential.

Introduction
The outbreak of the novel coronavirus (COVID-19) began in December 2019, and remains a prevalent threat around the world. COVID-19 is highly infectious and has high mortality, especially in patients with underlying health issues (such as diabetes). [1] At present, there is no specific drug for the treatment of COVID-19, and many potential therapeutic drugs have been included in the scope of clinical trials. Several institutions have focused on verifying the therapeutic effect of vitamin C on COVID-19. [2,3]

How Does High-Dose Vitamin C Help Treat Cancer?
High-dose vitamin C has been studied as a treatment for patients with cancer since the 1970s. A Scottish surgeon named Ewan Cameron worked with Nobel Prize-winning chemist Linus Pauling to study the possible benefits of vitamin C therapy in clinical trials of cancer patients in the late 1970s and early 1980's.
Surveys of healthcare practitioners at United States CAM conferences in recent years have shown that high-dose IV vitamin C is frequently given to patients as a treatment for infections, fatigue , and cancers, including breast cancer.
More than fifty years ago, a study suggested that cancer was a disease of changes in connective tissue caused by a lack of vitamin C. In the 1970's, it was proposed that high-dose ascorbic acid could help build resistance to disease or infection and possibly treat cancer.

Pięknie pachnie.
Kosmetyk pachnie cytrusowo, dosyć intensywnie. Kosmetyk jest żółtawy. Na skórze czuć drobinki, które masują moją skórę. Zauważyłam lekkie rozjaśnienie mojej skóry. Peeling stosuję regularnie eaz q tygodniu. Nie czuję podrażnienia ani uczulenia. Nie należy mocno masować skóry twarzy ponieważ może zaistnieć zaczerwienienie.

Bardzo fajny
Kupiłam ten peeling z przypadku i pozytywnie mnie zaskoczył.
Opakowanie proste, wygodne w użyciu.
Zapach delikatny, przyjemny.
Nie spowodował u mnie uczulenia ani wysuszenia.
Skóra po użyciu jest zdecydowanie wygładzona, czuć że została wypeelingowana. Nie jest pozdzierana. Konsystencja lekkiego kremu z malutkimi drobinkami ledwo wyczuwalnymi pod palcami, nie spodziewałam się że tak fajnie zadziała.
