Study University of Zurich


We carried out a number of studies with the University of Zurich that spanned several years from 2010 to around 2018.

Before the university conducted this study, many different animal species had been treated. The system could be used for both normal medicine and herbal products, but did it really work? It seemed like we had a random system. Similar to the electric car. It's been around for 75 years, it happens to be better and cheaper than anything else, but nobody wants to use it. So we had to outline what the university was supposed to find out in its studies, and that was the template:

Could our system and product actually:

- penetrate the skin non-invasively?

- reach the joint? - create a depot?

- supply the application area with oxygen?

- would it be stable and would produce the same results with several animals?

- Was it really painless to use? - was it really easy to apply?

- Did the animals recover faster?

With the exception of the last 2 points, we were also able to prove all of these points, even if this could only be partially assumed on the basis of a hypothesis. The system was not digital and not easy to use and we have now been able to solve this point by developing our new application system.

The speed of recovery has not been proven very well either. The animals were slaughtered relatively quickly after the operation. What we could see, however, was that the pain management was much more efficient with our system, which in turn hypothesizes that the wound is healing much faster than normal. (We have also had this experience with all open wounds) The first study started in 2010.

It was important that the animals used were of the same origin and age and that they grew up under identical conditions. In 34 sheep, a massive defect was created in the cartilage of the knee joint, and then so-called "microfractures" were punched into the bone. This approach has already been used in several earlier studies by the department and leads to osteoarthritis in the joint within a few weeks.

The animals were divided into six control groups and treated with Vetdrop TDA for six weeks. Product: Carprofen for All Groups - an anti-inflammatory agent believed to be effective in treating osteoarthritis. Standard group - here only carprofen was administered intravenously - this was the reference group as the intravenous methods are well known.

One group received no drug at all but was treated with Vetdrop TDA. Four TDA groups were formed, which were treated with different formulations in the TDA system (3 times a week). The different preparations were different phytoproducts that were either mixed with Carprofen or not mixed.

The blood values ​​of the animals were checked every two days, the joint values ​​more frequently at the beginning and weekly later. The pain behavior of the animals was also documented and examined. Six weeks after the last treatment (12 weeks after the operation) the animals were sacrificed and examined for changes in the cartilage and bone of the manipulated joint. The results were very clear: the indicator substance carprofen reached the joint center (synovial fluid) after the first TDA application. Reproducible and effective values ​​were achieved. The pain response observed in the animals treated with Vetdrop TDA was better than that of the control groups. The defect appeared to respond much more positively to any product administered with TDA than to intravenous administration.

An oxygen saturation test was carried out, but it was unsuccessful for technical reasons. The fact that even the group treated with no drug but treated with TDA performed better than the animals treated with intravenous carprofen suggests that the oxygen is able to penetrate the skin and close the blood cells activate as we suspected.

The results were so convincing that Nathalie Fouche did a second study and wrote her doctoral thesis, in which she came to similar conclusions as above, again with a better result with the TDA than with the intravenous administration So what can we get from the studies derive?

The system works.
