1.  Anti-inflammatory effect - This valuable natural product supports the organism in fighting inflammatory processes. The effect is noticeable in both local external and internal use.

2.  Antioxidant protection - due to the rich antioxidant content of the oil. Antioxidants support the neutralization of free radicals, which speed up cell ageing and cause a number of health issues.

4.  Immune support - Regular intake of black seed oil supports the self-protective capacity of the body.

5.  Cholesterol and blood glucose regulation - Some research suggests that high-quality black seed oil can help decrease the levels of LDL cholesterol and regulate blood glucose levels, which makes it especially useful for people with diabetes.

6.  Relief for respiratory infections - Black seed oil is used as a powerful remedy for conditions like asthma, sinusitis and different allergies.

Methods of treatment

This valuable product can be used both externally and internally, depending on the desirable effect. Liquid extracts which are safe for human consumption can be taken daily, on an empty stomach in the morning. People who do not like its specific taste prefer to take black seed oil capsules. They have the same effect and are easier to consume.

External local application is appropriate for treating acne affected skin, eczema, psoriasis and skin scars by direct application on affected areas. Rubbing the oil onto the skull skin can stimulate hair growth and decrease dandruff. When used to treat painful joints, slow, circular massage like rubbing onto the painful areas can reduce inflammation and improve blood circulation in the affected area.

How should black seed oil be taken?

Black seed oil can be taken in several different ways depending on the desired effect. For internal use, the commonly prescribed quantity is one teaspoonful per day, on an empty stomach, in the morning. You can mix it with water or bee honey. This is the generally accepted standard dosage but in case you are new to this practice, it would be wiser to start with half a teaspoonful and gradually increase the quantity to one teaspoonful per day.

Many people prefer taking the oil in the form of capsules, which are somewhat easier to use and the specific aroma is blocked. Regardless of the form, it is important to consult a medical expert before you introduce the oil into your diet, especially if you have chronical medical conditions or if you are on regular medication of a kind.

What are the contraindications to using black seed oil?

Despite the multiple benefits of black seed oil, it is important to note that different organisms can react in different ways to its effects. Its use is considered safe when consumed moderately1, whereas excessive or inappropriate consumption can lead to undesirable side effects such as:

● It can cause allergic reactions - Despite the fact that it can rarely happen, some people might get contact dermatitis after using black seed oil. So, before using it, it is recommended to perform a sensitivity test.

● It is not recommended for pregnant or breastfeeding women - Black seed oil can affect hormonal balance and cause uterus contraction, which makes it inappropriate for pregnant women. There is not sufficient data concerning its safety during breastfeeding.

● It can excessively reduce blood sugar levels - People with Type 1 and Type 2 diаbetes who regularly take blood glucose lowering medication should be careful because this oil can intensify their effect and lead to hypoglycemia.

● Effect on the blood pressure - Black seed oil can decrease blood pressure, which makes it inappropriate for people suffering from hypotonia as well as for people who regularly take blood pressure control drugs (antihypertensives).

● Risk of getting stomach upset - When taking high doses of black seed oil internally, it can lead to stomach discomfort, nausea or even diarrhea. To prevent this - start with small quantities and observe what your body’s reaction will be.

● Possible interaction with prescribed medication - If you take blood thinning drugs (anticoagulants) regularly, antidepressants or immunosuppressive drugs, black seed oil can affect their efficiency.

Proper storage of black seed oil

In order to preserve all valuable properties of black seed oil, it is necessary to consider some proper storage rules. This high-quality product is high in fatty acids, Thymoquinone and antioxidants, which are photosensitive, thermosensitive and prone to oxidation. Inappropriate storage can lead to oxidation and loss of its medicinal properties.

● Store in a dark, cool place - This product should be kept away from direct sunlight. Exposure to UV radiation can lead to quick decomposition of its active ingredients. It is also important to keep the oil in temperatures below 25°C - in a fridge or a cupboard maintaining a constant temperature within this range.

● Store in dark glass bottles - High quality black seed oil is sold in dark glass bottles which provide maximal protection against harmful UV radiation.

● Avoid contact with air - Make sure that you always put the cap back and close it well after use to diminish oxidation.

● Shelf life - Despite the fact that the antioxidant properties of the oil act as a natural preservative, it is still important to check the expire date on the bottle. It is usually between 12 and 24 months after opening the bottle. In case you notice any changes in taste or odour - discontinue use.

When stored under appropriate conditions, black seed oil will retain all its valuable properties and stay effective. Always choose cold-pressed oil, store it in appropriate conditions and make sure to use it within its shelf life.
