herbal tea for parasites

There are different ways to infect people with parasites. Statistics say that a common cause of death of people is the presence of parasites in the body and infectious diseases.

In blood plasma, scientists have found fungi, bacteria and even algae. The most common are intestinal worms.

Parasites are able to live inside a person for a long time. In 60% of cases, chronic and oncological diseases are caused by their vital activity. With prolonged exposure to microorganisms, the internal organs and the entire immune system suffer.

Methods of infection with parasites

There are different ways to get infected with parasites. Parasites are microorganisms that live at the expense of another organism and are biologically and ecologically related to it. Parasites can feed on fluids, tissues, products that a person consumes, remaining in the body temporarily or permanently.

You can get helminth infections in the following ways:

  1. Through dirty hands.
  2. In contact with the ground.
  3. For insect bites.
  4. If you eat a piece of uncooked meat or fish.
  5. If not, wash fruits and vegetables before eating.
  6. If contact is illiterate with animals.
  7. After contact with a person sick with helminth.

Worm eggs can be found in soil, water, dirty fruits and vegetables, and meat or fish that have not undergone adequate heat treatment.

In some cases, the infection can occur due to an insect bite, but it is extremely rare, as mostly helminth eggs enter the body with food. Dirty hands can also become a source of infection with helminthiasis.

You can also be infected by a sick person who is a carrier of worms. The breastworm crawls through the anus and lays its eggs in the anus. They, in turn, can remain in the underwear, being in the hands of one person. The larvae can stay in the toilet, on the front door handle, on other items. If the rules of personal hygiene are not followed, they penetrate into the body of other family members. If helminths are found in one of the family members, all family members should be treated.

Infection through water occurs by drinking unboiled water or washing.

What types of helminths exist?

The most common group of intestinal worms, which includes nematodes. These include snail worms, roundworms, needles, heartworms and trichinella.

The second large group includes protozoan or unicellular parasites. These are amoebae, giardia, neospores, cryptosporidiums, etc.

Entameba chistolytic infection can occur through drinking contaminated water. In this case loose stools appear, there is severe pain in the abdomen, vomiting. Sometimes in severe cases, such manifestations give a complication in the liver. People often confuse amoebic dysentery with a viral infection.

Millions of unicellular parasites can exist and develop in the walls of the stomach, which prevent the nutrients needed by the body from being properly absorbed.

Characteristic signs of giardiasis

The symptoms of parasite infection are as follows:

  1. Accumulation of gas in the stomach.
  2. Uneven stool with undigested food pieces.
  3. Chills.
  4. Increased sweating.
  5. Frequent abdominal pain.
  6. Liquid stools.

In the absence of treatment for parasites, over time, a person will start to lose weight and often get sick due to weakening of the immune system. Of course it is not advisable to be guided only by the symptoms to identify the parasites. It is necessary to perform a series of stool and blood tests to detect helminths. Treatment depends mainly on the degree of infection. In folk medicine, there are many recipes for the treatment of helminthiasis, in difficult cases it is better to turn to a medical method of treatment.

Classification of helminths

Worms are divided into flat and round.

Flat views:

  1. Trematodes, these include schistosomes, opisthorkis, etc.
  2. Cestoda - echinococcus, strip, alveococcus.

Roundworms or nematodes:

  1. Breast worm.
  2. Ascaris.
  3. Trichinella.
  4. Breast worm.

The following types of helminths are the most common.


This type of worm is heterosexual, on the outside it resembles a needle with a length of 0. 4 to 2. 6 cm. Females are considered large, which can produce up to 300 larvae per day.

Transmission routes are mostly being washed in polluted waters. Infection occurs through the mucous membranes of a person and by accidental ingestion of contaminated water during bathing. Once in the body, the larva turns into an adult within a day, capable of producing hundreds of similar organisms.

The schistosome reaches puberty after entering the human venous system with bleeding. An individual's eggs may be in the intestines, urine, mucosa. After a bowel movement, the schistosome begins its journey in the same way.

This parasite can stay in the human body for decades, causing irreparable harm to the patient. It is not the schistosomes themselves that are dangerous, but their eggs. They accumulate in the internal organs and cause damage to their nails, damaging the tissues, which often causes various ulcers.

There are symptoms with which a person can determine the presence of schistosomes in the body:

  • poor appetite;
  • anemia;
  • enlargement of the liver and change of the spleen;
  • poor intestinal motility;
  • stomach ache;
  • diarrhea or constipation;
  • acute weight loss;
  • bleeding in the intestines;
  • pain when urinating;
  • allergic reactions;
  • general weakness.


Cestodes are tapeworms that can reach gigantic lengths. So the length of an adult individual is on average 0, 5 cm The female of the cestoda is able to lay up to 200 thousand eggs during the year.

Due to special devices on the heads in the form of suction cups, cestodes are firmly attached to the intestinal walls. In this case, the whole body suffers. Such worms are especially dangerous for young children, as with their vital activity they deplete the body and in a short time cause anemia.

The routes of infection are fecal-oral, d. m. th. are dirty hands, fruits and vegetables. The larvae, once in the intestines, spread through veins throughout the body, penetrating the liver, heart, and even the oral cavity. A certain number of larvae die in this case, while the rest are swallowed again.

The main signs of parasitic infection:

  • nausea and vomiting;
  • yellowing of the skin;
  • pancreatitis;
  • frequent colds;
  • development of bronchitis and pneumonia.

Prevention of parasite infection

Since there are many ways to become infected with parasites, it is worthwhile to follow a few rules to protect yourself and your family members from the possible ingestion of worm larvae.

  1. Compliance with the rules of personal hygiene. Frequent hand washing will prevent parasites from entering the human body. Children in particular need to be taught this, as they often take different hands and objects in their mouths.
  2. Thorough washing of fruits and vegetables with running or boiled water.
  3. Extermination in the habitat of flying and crawling insects (flies, cockroaches), as they are carriers of helminth eggs.

Many experts believe that every person is a carrier of parasites to one degree or another, so you should cleanse your body from time to time.
