Anagallis Arvensis

It is about an European grass that has extended for many parts of the world. In South America he/she doesn't have communio and little name he/she is known; in Spain he/she receives the name of "Anagalia" and in France that of "Mouron des Champs." It is yearly or biennial, glabrous, of spread shafts and bottom-up, long from 10 to 60 centimeters, thin and of quadrangle section.

Their sheets are opposed, sometimes in verticilos of 3, sésiles, oval until oval-lanceoladas, they are long from 1 to 2 centimeters.

Their flowers are of color red minium or blue, from 5 to 8 millimeters of diameter, axillary, solitary, supported by thin peduncles, from 1 to 3 ½ centimeters long. Their corolla is rotácea, of 5 petals. 5 stamens. Gineceo of ovary súpero, spherical; I am used short.

The fruit is capsular (pixidio) of about 5 millimeters of diameter, with dehiscencia equatorial and numerous seeds.

It flourishes from October to November. He/she generally appears in fields, banks of roads, aborted lands and I eat overgrowth of gardens; still in the sandbanks of the coast platense.

It is used as medicinal from the antiquity, he/she has contradictory employments. Discórides praised to this grass against pains in general and especially quernstone pains, against humor of the nasal mucosas and the ulcers of the cornea. Also against chronic affections of the liver and kidneys.

It was formerly also considered as good detersivo and it was also used by the women to clean and to put smooth the complexion of the face. Others assure that it is toxic plant and that it can cause acute enteritis.

It seems to not be grass studied from the therapeutical point of view. For some it is used in decoction at the 20 for thousand giving good results to combat the asthma.

He/she also makes sure that their juice is corrosive and it can be used as sinapismos on the skin.

Although the infusion at the 10 for thousand, excites the secretion of the urination. It is also said that their tizanas was used with great success in the epilepsy. In Europe he/she had fame like antidote in the hydrophobia.

Allergy to the Medicines

In general terms, the answer of our organism to the entry of a chemical substance with therapeutical ends obeys a laws that are subject to the share farmacodinámica of the used medicine whose toxicity grade or harmfulness has been studied previously. But it is not room for doubt that, in a certain number of patients, this pharmacological share theoretically foregone it escapes from the orbit of the communio one and the individual responds from an accidental way to the oral or parenteral management of a medicine. Doing without more or less of theories ingenious and truthful, it is possible that the accidents caused by the medicines can be classified in the following way:
1-high grade of toxicity of the used medicine and whose symptoms show up in most of the cases.
2-certain patients, for different reasons and as soon as determined, but not related with the allergy, they don't tolerate, like it is current, the chemical substances. To procure a pharmacological desirable share, it becomes precise to be administered them to much pettier and more unusual dose. We speak then of intolerance.
3-in some occasions, the effects that are expected are absolutely cross to those that it was logical to wait. It is about a personal paradox and it is for example what happens, when when giving an antihistamínico that averagely produces drowsiness, the individual it responds with a nervous general excitabilidad, desorbitada and unforeseeable; we could speak then of idiosyncrasy, in the sense fully etymological of the word.
4-in other cases, the fellow can enter, immediately to the entry of the medicine, whichever it is the nature of this and the contact modality, a type of divorced reaction completely dela nature of the substance and of his share farmacodinámica. It connects it with what the physicians are accustomed to see when they speak of syndromes anafilácticos or allergic. The word allergy should be reserved for this reaction type that involves a sensitization; it doesn't import now, and here, if in the antecedents they are allergy traces or not, and if they believe to know or on the contrary to ignore, the mechanism humoral or cellular that has unchained it.
5-finally, it exists another group of patients that, in front of the entry of a chemical substance of the type medicine, they unchain shocks with circulatory immediate failure that you/they very possibly owe you to the release of a substance called histamine whose pharmacological affection is the responsible for the serious dysfunctions. The relationships that can exist among the lawsuit, the allergic etiology and the pathogenetic unchaining mechanism, the histamine, they cannot be described here.

Until another type of anomalous answers to the medicines, such as those that in fact show up when discontinuing them; still in case, until that moment, they were very supported; it constitutes it an answer rarity that, for the unusual thing, we only mention it.

The clinical boxs to that the allergy medicamentosa can give place are extremely varied, I eat for example: shock of the type anafiláctico that is the most serious in these accidents; syndrome similar to the illness of the serum; fever medicamentosa, possibly many times to the own antibiotics and whose appearance suspicion outlines the physician a therapeutical query quite difficult of resolving; alterations cellular hemáticas; asthmatic crisis, rinitis and allergic conjunctivitis; cutaneous manifestations, of the erythema type, urticaria, edema, eczema; and hepatic, renal and gastrointestinal alterations.
