Itching eruptions


Culex musca was proved by Kent but only a minimal entry is found in the Dictionary. The insect proved by Kent was probably Culex pipiens, the common house mosquito found in North America. A further proving was made by Dr Nandita Shah, Dr Sunil Anand and Dr Jayesh Shah in Mumbai. This is referred to as Culex musca but as some pharmacopoeias specify Anapheles fluviatis, the transmitter of Malaria, it may have been this species that was used. A further proving of the common New Zealand mosquito, Culex pervigilans, was conducted by Alastair Gray in Sydney in 2002. The provings gave very similar pictures and there does not seem to be enough difference between them to keep the entries separate. However, in the schema symptoms are indicated by (K) for the Kent proving (M) for the Mumbai proving and (S) for the Sydney proving.

The mosquito is a pest throughout the world and a vector for many diseases including: Dengue Fever, Yellow Fever, West Nile Virus, Eastern and Western Equine Encephlitides, La Crosse and St Louis Encephalitides and Dog Heartworm. The most notable mosquito borne disease is Malaria which is caused by the Plasmodium protozoa whose life cycle involves asexual reproduction in a host, which can be a mammal, a bird, a reptile or a human depending on the species of Plasmodium, and sexual reproduction in a species of Anopheles mosquitoes. The protozoa infest red blood cells bursting them to release the merozoites, daughter cells, and toxins and causing the malarial fever, which results in more than a million human deaths each year.

The bite of the mosquito involves the injection of salivary fluids that cause swelling and irritation.

The mosquito lays eggs that float on standing water, some species lay them individually, while others lay them linked in rafts. The eggs hatch into larvae after about 48 hours. The larvae, called wrigglers, live in the water feeding on micro-organisms and organic matter. The larvae come to the surface to breathe, often through a snorkel like breathing tube. They moult four times, the fourth instar becoming a pupa. Although the pupae do not feed they are unusual in that they are highly mobile and respond to light and threat by flipping their tales and tumbling, they are known as tumblers, into safer places and later floating to the surface again. After metamorphosis in the pupa the adult emerges and, after drying, takes to the air. Mosquitoes generally feed on nectar but the female requires a single, high protein blood meal in order for her eggs to develop. Mosquitoes tend to be crepuscular feeders, most active at twilight. Females emerging in late summer find a sheltered place after mating and hibernate over the winter emerging in the spring to lay their eggs. The life cycle of mosquitoes varies from 4 to 30 days depending on species and on temperature. Mosquitoes have four wings similar to the other Diptera but there are scales on them. The buzzing sound comes fro the very fast wingbeat which is slightly slower in the female.

There is often some question, particularly with animal remedies, as to whether the remedy represents the feeling of the substance or the effect that it has: the poison or the poisoner, the predator or the prey. The proving of mosquito conducted in Mumbai gives some indication of where the answer lies. In symptoms that were clearly consistent with the general proving picture, prover 4 recorded. "I was traveling by bus, it was very crowded. One lady touched my hair, that is very common, but I told her 'Can't you see?' I spoke rudely to her. The lady told me: 'If you are so fussy you better travel by first class.'" While prover 5 reported: "While traveling by train I happened to touch a lady, she made a face. I got irritated and told her, 'Why don't you travel by first class?'" This satisfying antithesis would seem to indicate that the remedy is about the point where contraries meet and are in conflict, about both sides rather than about either particular side of that conflict.

The feeling that was strongest in all of the provings was one of irritability. This was found generally in the physical symptoms from nose to anus and particularly in the skin symptoms, and almost universally in the mental and emotional symptoms.

Irritability leads to anger and a willingness to quarrel. Even in dreams they are quarrelsome. The anger could be extreme, even rage with a desire to kill and was almost always out of proportion to the offence which was often trivial. The provers felt that they were being taken advantage of, taken for granted or that people were invading their privacy and interfering. There was a strong response, a desire to retaliate and to fight back. Anyone that walked in my path I wanted to push and shove. The provers were rude, quarrelsome, intolerant and censorious. The rudeness and argumentative was worse sometimes at home than when out but it was consistent and widespread. Although there was a sentimental feeling about children; children were particularly irritating and there was a desire to shout at them or worse.

There is strong fear in the remedy. Fear of danger, of murder and of being attacked. That strangers would attack her from behind. There particularly a sexual fear of being attacked and raped. These fears were well represented in the dreams with dreams of war and being bombed of being attacked and of murder and rape. However, more unusual is the feeling of confidence, that she could take on whatever and whoever was after her and deal with them appropriately. She felt she could face anything. She was confident that whatever happened she could handle it herself.

In the dreams there is powerful feeling of having committed a crime, of having murdered someone. The guilty dreams were matched in waking life with a feeling that people looked on them as a criminal or thief.

As well as confidence and assertiveness there was a desire to be seen as the best. Attention to detail and to do things well. She wanted to gain knowledge, though for what it can do rather than for its own sake. She wanted to be the best prover and for everyone to recognize it. This appeared in dreams of being special, being the best, of winning prizes and of being praised. There was one dream of being powerful and killing a lion with a single blow. This sense of being the first and best may lie behind the dreams of the letter A in the Australian proving.

The desire to be seen or recognised as superior was found in a concern for appearance. A desire to be well dressed with the best clothes and the best jewellery. It is alright to be overdressed but one should never be underdressed. There was a desire or need to shop and a tendency to spend too much money. Concern for appearance was also found in worry about the hair which has a tendency to fall out.

In spite of the desire to be the best there is a strong apathy, an inertia and an unwillingness to do things, especially to start new things. Laziness and boredom prevail. As in many insects there is a tendency to exhaustion and particularly physical exhaustion while the mind remains clear and active. This is physically expressed as a heaviness as if they were dragging themselves around and in the eyes which are heavy with eyelids that can barely be kept open. The head and the lower limbs are also particularly heavy.

There is a feeling of detachment and separation. The body and mind feel separate and the person is separated from the world around. There is a desire to be alone that at least ameliorates the irritation caused by people. There is a numbness both emotional and a physical numbness felt in many areas, particularly the tongue and mouth.

There is mental confusion and forgetfulness and many mistakes particularly in writing.

Again as with insects in general there is extreme sensitivity, to sad stories, to the environment and to storms, though it is met more often with selfish irritability than with a desire to help.

Irritability can be discerned throughout the body. The nose in particular suffers from epistaxis, especially on waking, from fluid coryza and from sneezing. The itching is so severe that there is a desire to rub the end of the nose off.

Nausea is severe and pervasive. It is particularly found after eating and at meal times. It is worse for smells and for the thought of food.

Burning pains are found everywhere but are noticeable in the throat, stomach, urinary tract and anus. The dryness and burning in the throat and lungs causes a paroxysmal cough.

The stool requires straining and is incomplete.

Burning and itching is found everywhere on the skin and on the anus and genitals with a desire to scratch. There is a particular eruption that is red, raised and itching and about the size of a quarter.

There is burning heat but also burning cold and numbness. The skin can be cold and clammy.

Sleep is difficult and unrefreshing and many symptoms are worse in the morning, or worse during the day not ameliorating till the evening.

Discharges, saliva and perspiration are all clear and watery but they are also sticky.
