Infection is a condition that causes the invasion of stimuli and micropathogens, including viral infection.
Similar to bacterial infection, both infections share common characteristics by spreading through coughing and sneezing and contact with infected people, especially through kissing and sex.
However, unlike bacteria, a virus replicates only inside the living cells of an organism. Viruses can infect all types of life forms, including humans and microorganisms, such as bacteria and archaea.
Anti-viral effects are the process that which certain substances are used to cause the destruction of a virus.
In the acute phase of viral infection, depending on the types of viruses, the viruses after entering the body start to attack the specific host cells. The cold and flu virus will attack the cells in the respiratory system and the human immunodeficiency virus (HIV), which causes AIDS, will attack the white blood cells of the immune system,
The viral infection has been known to carry over some different stage, after successfully attaching to the host cell, the virus to release its mRNA into the host cell, leading to the recruitment of the host cell's enzymes to accelerate the viral multiplying, then breaking free from the host cell to start the cycle all over again.
The white blood cells in the systematic immune response in the acute phase of infection stimulate the production of the proinflammatory cytokines to the site of infection with an aim to protect our body by killing off the invaders.
The battle between the immune white blood cell and viral invaders in most cases is in the flavor of the side of the immune system, the invaders are killed and the infection is healed.
However, if the immune system can not kill off the invaders within 3 - 8 weeks, it then will adapt to the change, leading to chronic inflammatory and infectious diseases.
Dengue virus (DENV) belongs to the Flavivirus genus and is transmitted by Aedes aegypti and Ae. Albopictus mosquitoes, found in tropical and subtropical regions of the world. In severe cases, dengue virus serotype 2 has been found to induce symptoms of severe plasma leakage, severe hemorrhage, and/or severe organ impairment.
Dandelion is a herbaceous perennial plant, genus Taraxacum, belonging to the family Asteraceae, native to temperate regions of the world. It has been used in traditional and herbal medicine to treat gout, eczema, acne, gall bladder, kidney, liver, and urinary disorders, hypoglycemia, dyspepsia with constipation, edema, blood pressure, and heart weakness, chronic joint, skin diseases, etc.
On finding a natural ingredient for the prevention and treatment of infectious diseases, scientists examined the cytotoxic concentration and the inhibitory effect of extracts or fractions from Urtica dioica, Taraxacum officinale, Calea integrifolia and Caesalpinia pulcherrima on the dengue virus serotype 2 (DENV2 replication on the BHK-21 cell line.
According to the tested differentiation,
* The methanolic extracts at 60 °C of T. officinale and U. dioica showed higher inhibitory effects on DENV2 replication.
* The chemical analysis suggested that the higher activity fraction is found for U. dioica and T. officinale, at the IC50 values of 165.7 ± 3.85 and 126.1 ± 2.80 μg/ml, respectively.
The compounds which exhibited the efficacy of T. officinale were luteolin and caffeoylquinic acid derivatives and quercetin diclycosides compared to the compounds in the active fraction chlorogenic acid, quercetin derivatives and flavonol glycosides (quercetin and kaempferol) in the U. dioica.
Based on the results, researchers suggest, "Two fractions from U. dioica and T. officinale methanolic extracts with anti-dengue activity were found. The compounds present in both fractions were identified, and several recognized molecules have demonstrated activity against other viral species".
Dandelion may be considered an antioxidant remedy for the treatment of dengue virus serotype 2, pending confirmation of the larger sample size and multicenter human study.
