The following herbs widely used for infections and the flu are a part of phytotherapy for diseases that affect a single body part or system and the entire body. These herbs help to heal infectious diseases in three ways:

- Antibiotic action: Natural antibiotics in superior plants do not act as quickly and effectively as chemically treated, purified antibiotics in pharmaceutical products. However, they are much better tolerated since they generally lack any side or toxic effects. Moreover, they do not depress natural defenses, as pharmaceutical antibiotics usually do. Plants also contain antiseptic substances that act on the skin or mucosa surface.
- Depurative action: Herbs promote elimination through the kidneys, the skin, and the liver of toxins our bodies continuously produce, especially with infectious diseases.
- Immunostimulant action: Some herbs can stimulate the immune system, which produces defenses against infections. These defenses are double: cellular (for instance, the leukocytes or white blood cells) and humoral (antibodies). Both increase in number with phytotherapy remedies.
In the fight against diseases, the herbs widely used for infections and the flu act mainly organically, improving their conditions to allow the body to confront the germs by itself. Remember that the best antibiotic will fail if the body’s defense mechanism is ineffective.
Herbs Widely Used for Infections and The Flu
Perspirant Plants
These plants stimulate sweat production. Sweat has a composition similar to urine, though less concentrated. Perspirant plants have a notable depurative and antitoxic effect on the blood. They are recommended for infectious or febrile diseases, overload due to excessive diet, arthritis caused by an excess of uric acid, and chronic toxicity.
Herbal teas derived from medicinal plants are excellent for promoting the body’s healing during recovery from infectious diseases: they help eliminate toxins, tone the body, and increase appetite.
Fighting the microorganisms that cause infections is insufficient to achieve a healthy, infection-free body. Current medicine is more critical to the body’s fight against infectious diseases. Its use and adopting a healthier lifestyle can help us more than the most potent antibiotic.

List of Infectious Diseases
Herbs widely used for infections and the flu can improve the health of people suffering from infectious diseases at any point in their lives.
Low defenses – An unhealthy diet, lack of physical exercise, and abuse of antibiotics are some of the causes that can depress the immune system. In other cases, lack of defense is caused by severe ailments such as AIDS or certain types of cancer.
Besides correcting the causative factors, these plants have a notable immunostimulant effect whenever possible. Their use is recommended in any case of severe infection, and depression is a defense against infections when they occur.
Febrile diseases – In any case of fever, the causative illness diagnosis is required since many can cause fever. Hence, a specific treatment could be applied. These medicinal herbs are a complement to the treatment of fever-causative disease. They not only produce a decrease in temperature but also increase perspiration, promote the elimination of toxins, refresh, and invigorate. Therefore, they are better than antipyretic medicines.
Convalescence is an intermediate period between illness and health during which our body corrects the losses suffered and normalizes the altered functions. The term is generally applied to the phase of recovering from any infectious disease. Phytotherapy uses important plants to ease and shorten the convalescence process. These plants complement other measures such as diet or physical rehabilitation.
Amebiasis is a disease caused by amoebas and protozoa (unicellular animals). They provoke severe diarrhea (amebic dysentery) and hepatic afflictions. Some pharmaceutical preparations are made from the extract of this tropical shrub.
Brucellosis is an infection caused by Brucella mellitensis, transmitted through milk and dairy products (goats and sheep). In addition to pharmaceutical preparations, herbs help heal this disease.
Cholera is a disease caused by choleric vibrion, which manifests as vomiting, liquid diarrhea, and dehydration. This plant helps with healing and is also used for antibiotic treatment. See also herbs for gastroenteritis.
Diphtheria is a children’s disease caused by the diphtheria bacillus. It affects the throat (pharynx and larynx) and the nose and can cause asphyxia. At present, this disease is quite rare. Applications with lemon juice complement its specific treatment.
Salmonellosis – This disease is caused by bacteria of the genus Salmonella, which are present in food in harmful conditions. It manifests itself as severe gastroenteritis. Besides these plants, those recommended for gastroenteritis are useful.
Syphilis is a sexually transmitted disease caused by the bacteria Treponema pallidum. These plants complement specific antibiotic treatments.
Typhoid fever is caused by the bacteria Salmonella typhi, which can be found in infected water or foods, especially seafood. It appears as severe diarrhea and intoxication. These medicinal herbs have a positive influence on the course of this disease.
Whooping cough is a disease caused by the microorganism Bacillus pertussis. It manifests itself as crises of spasmodic cough that repeat for several weeks. These herbs effectively ease cough and promote this disease’s healing. See also the herbs recommended against cough.
Influenza is an infectious disease caused by a virus. It manifests as fever, muscular pain, respiratory catarrh, and a tendency toward bronchial and lung complications. There is no specific pharmacological treatment for influenza. The best one is helping the body overcome the infection by enhancing its healing mechanisms.
Phytotherapy acts precisely in that way. These medicinal herbs increase sweat and thus eliminate toxins and stimulate immune defenses against infection. They also decrease fever and alleviate the discomfort caused by the disease.
AIDS—Although some people have stated that using these herbs can heal this terrible ailment, they can positively help its evolution by stimulating our body’s abilities to fight against this disease. Increasing our body’s defensive capacity seems to be the best way to heal AIDS since its virus has not been eliminated with medicines. These herbs, along with a healthy lifestyle, can do their best to fight AIDS.
Tuberculosis is an infection caused by the Koch bacillus, Mycobacterium tuberculosis. It is a slow-progressing disease, mainly affecting the lungs, and manifests itself or becomes more severe when there is an imbalanced diet or unhealthy lifestyle. Herbs widely used for infections and the flu cannot heal this disease alone, but they promote the body’s healing mechanisms, which greatly influence the prevention and cure of tuberculosis.
Malaria is an infection caused by protozoa (unicellular animals) of the genus Plasmodium, transmitted by a mosquito bite. According to the WHO, this disease affects most people worldwide. Medicinal herbs widely used for infections and the flu are essential in treating malaria since antimalaria medicines are all quinine derivatives. This substance is removed from the bark of the cinchona tree, native to South America.

Fighting the microorganisms that cause infections is insufficient to achieve a healthy, infection-free body. Current medicine is increasingly critical to the body in combating infectious diseases.
Medicinal herbs widely used for infections and the flu do not act by destroying microorganisms but rather by strengthening the body’s defenses. Their use and adoption of a healthier lifestyle can help us more than the most potent antibiotics.
Herbal teas of medicinal herbs widely used for infections and the flu complement the treatment of infectious diseases during their acute phase and recovery.
