The COVID-19 pandemic has posed an unprecedented global health challenge, necessitating the exploration of various preventive and therapeutic measures. In this context, traditional medicinal plants and herbs have garnered significant attention for their potential in managing viral infections. Ajwain (Carom Seed), an aromatic spice commonly used in culinary preparations and traditional medicine, has emerged as a subject of interest due to its reported antiviral properties. This paper provides an overview of the current research and knowledge regarding Ajwain's potential role in combating COVID-19. It discusses the phytochemical composition of Ajwain, highlighting compounds such as thymol, which have demonstrated antiviral and immunomodulatory properties. Additionally, this overview explores the mechanisms through which Ajwain may exert its antiviral effects, including inhibition of viral replication and enhancement of the host immune response.


COVID-19, Ajwain, Phytochemical.


The World Health Organization (WHO) has declared the coronavirus disease 2019 (COVID-19) a pandemic. A global coordinated effort is needed to stop the further spread of the virus. A pandemic is defined as “Occurring over a wide geographic area and affecting an exceptionally high proportion of the population.”[1] We have now reached the tragic milestone of one million deaths, and the human family is suffering under an almost intolerable burden of loss [2]. The ongoing pandemic of COVID-19 has forced the governments to impose a lockdown, and many people have suddenly found themselves having to reduce their social relations drastically [3]. It causes serious lower respiratory failure, as in previous examples, and may damage the central nervous system in the early period, unlike the previous ones .It is proven that the virus is transmitted by airborne droplet infection and through contact with infected surfaces. The period between the introduction of the virus into the body and the onset of symptoms is called the incubation period, which is about 4 to 7 days in the majority of cases and can vary from 2 to 14 days when COVID-19 is concerned.10 Symptoms include fever in 80 to 90% of cases, cough in 60 to 70% of cases, gastrointestinal complaints in 40 to 50%, loss of smell in 30 to 40% and shortness of breath in 20%.11 Not all these symptoms are necessarily observed.

In December 2019 the first cases for COVID-19 infections were reported [4]. From 18th December, 2029 to 29th December 2019, 5 patients having acute respiratory distress syndrome were hospitalized among which one patient died [5]. Up to 2 January 2020, 41 patients were identified to possess laboratory confirmed COVID-19 infection. Almost half of these patients had underlying diseases particularly cardiovascular diseases, hypertension and diabetes [6]. It was believed that these patients were infected in hospital possibly due to nosocomial infection. Thus it was concluded COVID-19 is not a super-hot spreading virus but it most likely spread as many patients get infected by unknown mechanisms at different locations in the hospital.

Coronavirus disease symptoms (COVID-19)

COVID-19 affects different people in different ways. Most infected people will develop mild to moderate illness and recover without hospitalization.

The most common symptoms of COVID-19 are fever, dry cough, and fatigue.

Other symptoms that are less common and may affect some patients includes loss of taste or smell, nasal congestion, conjunctivitis (also known as red eyes), sore throat, headache, muscle or joint pain, different types of skin rash, nausea or vomiting, diarrhea, chills or dizziness [7].

Symptoms of severe COVID‐19 disease include shortness of breath, loss of appetite, confusion, persistent pain or pressure in the chest, high temperature (above 38 °c).

Other less common symptoms are irritability, confusion, reduced consciousness (sometimes associated with seizures), anxiety, depression, sleep disorders, more severe and rare neurological complications such as strokes, brain inflammation, delirium and nerve damage [8].

The carom seeds botanical name Trachy spermumammi belong to the family of Apiaceae (Umbelliferae), of the genus; Trachyspermum.

The phytochemical constituent of ajwain includes iron, calcium, cobalt, phosphorous, copper, magnesium, iodine, riboflavin, nicotinic acid and thiamine. The ajwain seeds are also famous for their essential oil. The seeds comprise of 2.5- 5% essential oil.

• Iron: Iron is an essential element for blood production. About 70 percent of your body's iron is found in the red blood cells of your blood called hemoglobin. It is primarily involved in the transfer of oxygen from the lungs to tissues. It also plays a role in metabolism as a component of some proteins and enzymes.

• Calcium: The body needs calcium to maintain strong bones and to carry out many important functions. Almost all calcium is stored in bones and teeth, where it supports their structure and hardness. The body also needs calcium for muscles to move and for nerves to carry messages between the brain and everybody part.

• Cobalt: Cobalt is only in the body as part of vitamin B-12. It's needed for making red blood cells (erythropoiesis). Cobalt has some of the same jobs as manganese and zinc. It can replace manganese in activating several enzymes.

• Phosphorous: The body needs phosphorus to build and repair bones and teeth, help nerves function, and make muscles contract. Most (about 85%) of the phosphorus contained in phosphate is found in bones. The rest of it is stored in tissues throughout the body. The kidneys help control the amount of phosphate in the blood.

• Copper: Copper works with iron to help the body form red blood cells. It also helps keep the blood vessels, nerves, immune system, and bones healthy. Copper also aids in iron absorption [10].

• Magnesium: Magnesium is a cofactor in more than 300 enzyme systems that regulate diverse biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation. Magnesium is required for energy production, oxidative phosphorylation, and glycolysis.

• Iodine: Iodine is a mineral found in some foods. The body needs iodine to make thyroid hormones. These hormones control the body's metabolism and many other important functions. The body also needs thyroid hormones for proper bone and brain development during pregnancy and infancy.

• Riboflavin: Riboflavin (vitamin B2) works with the other B vitamins. It is important for body growth. It helps in red blood cell production. It also aids in the release of energy from proteins.

• Nicotinic acid: Also known as vitamin B3 or nicotinic acid, niacin is one of eight B vitamins. Like all B vitamins, niacin plays a role in converting carbohydrates into glucose, metabolizing fats and proteins, and keeping the nervous system working properly.

• Thiamine: Thiamin (vitamin B1) helps the body's cells change carbohydrates into energy. The main role of carbohydrates is to provide energy for the body, especially the brain and nervous system. Thiamin also plays a role in muscle contraction and conduction of nerve signals [11].

An example on evaluation of antiviral activity of essential oil of ajwain against virus

Japanese encephalitis is a leading form of viral encephalitis, prevalent mostly in South Eastern Asia caused by Japanese Encephalitis Virus (JEV). It is transmitted by the mosquitoes of the Culex sp. The disease affects children and results in 50% result in permanent neuropsychiatric disorder. There arises a need to develop a safe, affordable, and potent anti-viral agent against JEV. This study aimed to assess the antiviral activity of ajwain (Trachyspermum ammi: Umbellifereae) essential oil against JEV.

Materials and methods: Ajwain oil was extracted by distillation method and in vitro cytotoxicity assay was performed in vero cell line by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay method. JEV titer was determined by plaque assay and in vitro antiviral activity of ajwain oil was quantified by the Plaque Reduction Neutralization Test (PRNT).

Results: Cytotoxic concentration of the oil was found to be 1 mg/ml by MTT assay. The titer of the virus pool was found to be 50× 10(7) PFU/ml. we observed 80% and 40% virus inhibition in 0.5mg/ml of ajwain oil by PRNT method in preexposure treatment and postexposure treatment (antiviral activity), respectively.

Conclusion: Our data indicate ajwain oil has potential in vitro antiviral activity against JEV. Further, the active biomolecule will be purified and evaluated for anti-JEV activity and also to scale up for in vivo trial to evaluate the efficacy of ajwain oil in future [14].
