Nowadays, there is a worldwide growing interest in the use of medicinal herbs or plants in the treatment of various diseases due to their promising results and fewer side effects. According to the World Health Organization (WHO), 60-80% of the world’s population particularly in developing countries, depends on herbal remedies or traditional medicine for their primary health care and treatment. One of the top ranked evidence-based herbal medicines, includes Nigella sativa which has been described as the ‘miracle herb of the century’. Nigella sativa is an annual flowering plant also called black cumin, black seed, or Habbatul Barakah is native to the south and southwest Asia and is cultivated in several countries in the Mediterranean region, South Europe, Syria, Turkey, and Saudi Arabia.
Historically, ancient Egyptian and Greek physicians used black seeds in the management of several diseases, such as headache, toothache, congestion of the nose, intestinal worms, promotion of menstruation, and production of milk. According to the Muslim population, the Prophet Mohammad said “use the black seed regularly because it is a cure for every disease, except death”. Thereby explaining its extensive use by Muslims all over the world
Extensive research has been carried out on the black seed and it has been noted that it has high nutritional content as well as pharmacological benefits. The seeds are rich source of carbohydrates, fats, essential amino acids and vitamins. The most active medicinal component of the seed is thymoquinone which has been seen to have the following medicinal properties and have traditionally been successful in treating the following:
- Anti-microbial (antibacterial, antiviral, antifungal) – Used topically and orally as a disinfectant on wounds
- Anti-inflammatory – For rheumatoid arthritis
- Analgesic – As a pain reliever for headaches and tooth aches
- Anti-hypertensive – Lowers cholesterol
- Hypoglycemic – Regulates blood sugar in diabetic patients
- Anti-carcinogenic – prevents proliferation of cancer cells and promotes apoptosis or death of cancer cells
- Antioxidant – Boosts immune system
- Histamine release inhibitor properties – For treating asthma and respiratory problems
Black Seed Oil Benefits in Oral Health Care
Oral health and the integrity of the oral cavity are crucial to the general health of human beings. Many oral diseases can be prevented and for many years, the use of plants, oral health care, and therapeutic practices have been closely related.
Black seed oil been documented in numerous scientific papers for its anti-inflammation and anti-bacterial benefits from the molecule Thymoquinone to help maintain healthy gums. Helps to lubricate oral surfaces, bringing relief to dry mouth sufferers.
Upon further research, some studies and clinical trials were conducted whose findings have shown how black seed oil has been successful in treating the following dental issues:
- Reduce Dental caries- Dental caries is primarily caused by the breakdown of sugars in to acid in the mouth by a class of bacteria called streptococcus Mutans. It was found that the black seed oil extracts not only had a bactericidal effect against S. mutans but were also seen to inhibit the adherence of S. mutans to the surface of the teeth reducing plaque formation.
- Reduce Periodontal and gingival diseases – shown to have antiplaque activity (results were equivalent to, synergistic with, or even better than the regularly used antibiotics, such as amoxicillin or tetracycline).
- Prevent nerve/pulpal inflammation when applied directly to the inflamed nerve. Can be used to replace formacresol in pulp capping in pediatric dentistry.
- Accelerate the healing of mouth ulcers and mucositis especially those induced from chemo and radiation therapy
- Expedite bone healing at dental extraction and surgical sites (suitable for all wound healing)
- Improve Osseo-integration of dental implants into bone which is fundamental for the long term success of the implant.
- It has been shown to have a 4-fold potential effect when used with certain antibiotics. This makes Black Seed oil an excellent choice for treating antibiotic-resistant infections.
- Antifungal activity – For treating skin infections caused by candida albicans systemically or topically (recommended to use a carrier oil with it)
Conclusion and Recommendations
Since there has been a great rise in replacing conventional treatments with herbal medicine, black seed oil owing to its immense health benefits and zero side effects, proves to be a popular choice to treat various diseases and conditions. Not only is it widely available but is also relatively cheap and affordable to acquire. Also, since there has been an alarming rate in antibiotics becoming resistant it is of critical importance that alternate medicine options need to be considered. Fortunately, lab studies have shown that thymoquinone from black seed extracts showed results which were equivalent to or even better than amoxicillin and tetracycline (widely used antibiotics).
Incorporation of black seed oil in to our everyday diet as well as in oral hygiene and therapeutic agents should be encouraged as it has shown to have positive long term effects. SprinJene tooth paste takes pride in its 100% natural and organic ingredients which include this miracle seed oil. Therefore, it highly recommended for people who are looking to shift toward healthier living, and especially in patients suffering from the above-mentioned diseases and conditions as they can benefit from its non- toxic, natural advantages.
