Well , in the popular culure , witches transform people in frogs ,have frogs as a pets , use frogs to cast spells ... But in real life i see , connections beetwen frogs and wicca , necklaces in the form of that animal , reports that people who started practicing Wicca found frogs close to home with frequency. So whats the relation beetwen that amphibian and wicca ?
Frogs, expectedly, are seen all throughout different myths and folklore from many cultures of dozensof different time periods because they are seen on every continent except Antarctica. Often they are associated with negative entities but in some cases they are also portrayed in a positive light, take for instance the Rig Veda creation myths. When talking about how the frog became associated with witches, historicallypractitioners would actually incorporate a toad's poisonous secretions and even body parts into'spells' and potions. In turn, religious individuals who had a demonized idea of"witchcraft" now associated frogs with the witches, which meant they are not of god and gave them a negative stigma altogether. Essentially, the same can be said for many other things such as certain herbs, symbols, and black cats.
As far as why it's still regularly incorporated into modern dayWiccaand why some report attracting frogs, I feel as though it may be somewhat self-explanatory. To put it simply, no matter what religion you follow or what you want to call it, magic is the manipulation of energy to produce an outcome of your favor. Generally. Whatyou put out into the universe you often receive back,so perhaps due to the connection that has been built between modern-day Wicca and the amphibians, when you venture into the Wiccan religion you may be attracting that energy and the appearance of frogs.
When performing spells or rituals, it often helps to use tools that assist in channeling the energy, such as candles, symbols, or the use of a particular herb. When it comes to the herbs, many of them have physical as well as spiritual benefits. Similarly, frog poison was not only used in witches' brew, but was also frequently dried and used to treat a variety of different ailments. What spiritualeffects/benefits it may provide and why some spells may call for it, I'm not positive but I do know that some cultures consider the creatures good luck and associate them with protection, fertility, and even rain. In addition, some frog secretions are known to produce hallucinogenic effects in humans and Shamans often used this early form of psychedelic to achieve altered states of mind, much like how they use Ayahuascaor DMT today.
In conclusion, I think much of the publicized phenomenon is due to therapid growth of Christianityand its stigmas/superstitions, but there is usually some form of truth behind myths and folklore. Frogs likely play a role in channeling energy for rituals and other forms of spell casting in addition to their other qualities. If you align yourself with them, they may appear more often.
