The potency of the black seeds was paired against several antibiotic agents such as tetracycline, amoxicillin, and Gatifloxacin. The study found out that out of the total strains studies, 97 of them were sensitive to black cumin. Most of these strains were resistant to the antibiotic agents.

Chemical Components Found In Black Cumin Seeds

Black cumin seeds are rich in phytochemicals that are responsible for their therapeutic effects. A study that was conducted on the effects of black cumin seed oil on different human pathogens found out that thymoquinone is highly effective against fungal infections caused by organisms such as yeasts and dermatophytes.

Thymol showed high activity against molds. Thymohydroquinone was also found to have activity against yeasts and dermatophytes.

The study discovered that the chemical constituents found in black cumin seeds are not useful only individually but also collectively. The study concluded that molds and fungus cannot survive in the presence of these chemical compounds. Researchers have been investigating thymoquinone since the 1960s.

The chemical component has several therapeutic effects such as anti-inflammatory, antioxidant, and anticancer. Besides its ability to preserve antioxidant enzymes S-transferase and glutathione peroxide, thymoquinone also acts as a free radical scavenger.

Thymohydroquinone is a potent acetylcholinesterase inhibitor. They block the activity of the enzyme preventing the degradation of the acetylcholine enzyme. As a result, the amount of time and activity of the acetylcholine enzyme is enhanced.

As a result of its inhibitory activity against acetylcholinesterase enzyme, Thymohydroquinone is used importantly in the management of several disorders including autism, dementia, and glaucoma among others.

Thymol is the chemical constituent that gives black cumin seed its therapeutic properties. It has tuberculocide and virucides activities. It is also used as a disinfectant for both medical and general purposes. Thymol also has culinary uses. They can be utilized for food flavoring and even in cosmetics.

The study concluded that thymoquinone is effective when it is combined with chemotherapeutic agents against the different cancers. The study also revealed that thymoquinone reduced the toxic effects of chemotherapeutic agents. Cell studies have also found out that black cumin’s effects against colon cancer growth is comparable to chemotherapeutic agents. However, black cumin has fewer side effects compared to the anticancer agents.
