Cantharis Vesicatoria Dosage, Potency and Repetition

Homeopathic medicines are prescribed based on symptoms similarity. The symptoms presented by the patient are matched with the symptoms of the remedy.

Depending on the extent of symptom similarity, the potency and repetition are decided.

The more significant number of symptoms that match, the higher is the potency used. Similarly, if fewer symptoms are matching with the remedy, then a lower potency is used.

Cantharis 30C

This is a potency reserved for cases where Cantharis is given as a purely therapeutic dose. The symptoms presented by the patient help the doctor to make a diagnosis of the disease, but they show less matching with the symptoms of Cantharis as such.

This dose needs to be repeated frequently, like 3 to 4 times a day.

Cantharis 200C

This potency should be used when the symptoms of the remedy match well with the person’s symptoms. This potency calls for a lot of symptoms peculiar to Cantharis to be present.

200C is repeated infrequently.

Cantharis 1M

This is a very high potency and should be used cautiously. It has to be used only when the entire picture of Cantharis fits perfectly to the T with the symptoms that the patient describes.

Ideally, 1M is prescribed as a single dose, and then it is advised that one waits and watches the developments that occur.

Cantharis Ointment

Cantharis, as an ointment, finds a significant place to occupy in a homeopathic first aid kit. A topical application of the cantharis ointment is made as an emergency treatment in burns, scalds, shingles, and insect bites.

One can also make the topical application by mixing a few globules of cantharis 30C in a few drops of clean and hygienic water.

Cantharis Tincture

The tincture of Cantharis is used in severe cases of urinary infection or extremely painful cases of burns and shingles.

A few drops of the tincture have to be mixed with water and consumed.

The tincture is highly potent and capable of creating toxic reactions; hence, it is advisable to use this form of medicine judiciously.

Cantharis Vesicatoria Side Effects

Cantharis is made using the toxin Cantharidin that is obtained from the Spanish fly.

This toxin is diluted to such an extent that all its toxicity is removed, and the curative properties are enhanced. This is done by the process called Potentization.

This process of potentization is the hallmark of homeopathy. Due to this process, the remedies are said to be gentle, safe, and effective, and with no side effects.

However, there may be cases that qualify to be called ‘side-effects of cantharis.’

These cases happen when-

1. The medicine has been given incorrectly.

2. The medicine has been given in a dose higher than what was required.

3. The medicine has been repeated more often than was required.

4. The person is compassionate physically.

So how does one come to know of the side-effects?

For this, one has to keep a watch on the symptoms. If they worsen after having been lessened for a while, it means that the remedy has been repeated unnecessarily.

Ideally, wait for the person to ride out the symptoms if they are not too severe. If the person cannot bear the complaints, then it is advisable to antidote Cantharis with a suitable remedy.

If new symptoms like a burning pain, itchy blisters, an increase in the frequency and desire to urinate, extreme rage, violent behavior are seen, it means that Cantharis wasn’t the proper remedy to be prescribed.

The newly developed symptoms are because Cantharis has acted wrongly and produced its toxic effects by being misused. Here again, immediate antidoting is the proper course of action.
