This proves that homeopathy acts on in-vivo models in the laboratory
Experiment :
In its natural state, the thyroid hormone thyroxine plays a vital role in the metamorphosis of tadpoles into frogs. Researchers observed the effect of a homeopathic solution of thyroxine on the development of tadpoles into frogs.
Tadpoles are separated into two separate groups:
- the first group is treated with water (control group)
- the second group is treated with a homeopathic solution, namely a diluted and succussed solution that is prepared using thyroxine: Thyroxine 30 DH.

Result :
The development of tadpoles into frogs is significantly slowed down in the group treated with the homeopathic solution of thyroxine.

- The experiment is repeated several times, always with the same statistically significant results.
- These results are confirmed by 7 independent laboratories.
- These results are obtained for a high dilution level: Thyroxine 30 DH (for which, in theory, there are no more molecules).
- Homeopathic solutions are generally obtained after successive dilutions to tenth (DH) or hundredth (CH). Each dilution is followed by a succussion step.

The presented data can, under no circumstances, be extrapolated to any property or clinical use in humans that would require additional studies.
