Lin Xiaoling (Dean of Han Shi Anti-aging Medical Center) chose essential oil, and the concentration is the key. Black seed oil contains about 1% essential oil. Oral oil can protect gastrointestinal mucosa, improve the discomfort of flatulence, and achieve the effect of treating digestive system diseases. Both smearing and oral administration can relieve bronchial asthma and cough. However, not all nigella seed oil can achieve the same effect, and the most important component of nigella utility lies in the value of thymoquinone. The content of thymoquinone plays a decisive role in the efficacy of nigella seed oil. The content may not be readable from the label, but it can be roughly judged from the taste of the entrance. The higher the thymoquinone content, the more pungent it can be. In the study of thymoquinone concentration and cytotoxicity of renal cell carcinoma, it was found that with the increase of thymoquinone concentration, the metastasis and invasion ability of renal cell line and the role of epithelial-mesenchymal transition were obviously inhibited, thus reducing metastasis. In contrast, if it is a low concentration of thymoquinone, it may have no effect on cancer cells. (Editor's recommendation: the oil-free diet is unqualified! It's good for the heart. You should eat these oils. The study of thymoquinone also confirmed that thymoquinone has a strong toxic effect on SASVO3 (a head and neck squamous cell carcinoma cell line that causes high deterioration), and the cytotoxicity of the cells increased with the increase of the concentration of the treatment drugs. In the study of the treatment of pancreatitis, scholars have studied the inhibitory effect of thymoquinone concentration combined with gemcitabine in the treatment of cancer on the apoptosis induced by the proliferation of BXPC-3 cells in pancreatitis during chemotherapy. Besides confirming that thymoquinone can enhance the inhibitory effect of gemcitabine on the growth of pancreatic cancer cells in vitro, the concentration of thymoquinone is also the key point whether thymoquinone is effective enough. There are many black grass seed oil products on the market, which come from different farms in different countries, whether in Egypt, Nigeria, Germany or the United States. Whether the oil products are certified organically is not the primary consideration, but ensuring that agricultural products are non-toxic can ensure food safety. (Editor's recommendation: Is mustard oil poisonous? Professor Sun Luxi: The body needs good oil, so it can be used for cooking. ) In terms of use function, some black grass seed oil is used as aromatherapy essential oil, while others are used as cooking oil for seasoning. Further, it is to advertise the thymoquinone concentration in the oil. Because these products have been developed for many years, most of them are reliable in composition. Black grass seed oil with low thymoquinone concentration can be used as a daily dish, or it can be dropped into drinks to increase flavor. Higher concentration can be used to apply to the body as moisturizing; Higher concentration of nigella seed oil has health care function and can be taken directly for maintenance. Several medical patents discovered by academic research need to be extracted, concentrated and refined in order to obtain better quality. Please consult a professional.

The use of good oil should be classified. Thousands of academic papers have affirmed that black grass is helpful to human health, and the best essence is black grass seed oil. So, should all household oils be replaced directly? Actually, it is not like this! The optimum oil temperature range of black grass seed oil is below 49℃. Besides cold and warm dishes, the best cooking methods are appetizing, cold dishes, cold food, or pickling and soaking vegetables with oil. The unique sterilization effect can also keep food fresh for cold food conditioning. In Mediterranean cuisine, fried meat, stew, sausage, meat sauce and other dishes are decorated with some black grass seeds, which make the dishes more delicious. Different oils have different conditioning temperatures and make different contributions to cooking methods. For example, butter, lard, palm oil and rapeseed oil are all high-temperature oils with high smoke point, high stability and high saturation. They are suitable for frying, frying and frying, and can make the taste crisp outside and tender inside at high temperature, while retaining the freshness and sweetness of the ingredients. The oils used for frying, frying, stewing and roasting are moderate temperature oils, such as olive oil, peanut oil, sesame oil, soybean oil and sunflower oil. It is the characteristic of this oil that the ingredients appear crisp but not soft and rotten under fast frying. Wheat germ oil, pumpkin seed oil, flaxseed oil and perilla oil are all low-temperature oils, which are mostly used for cooking such as water frying, boiling, stewing, boiling and roasting. The cooking method of gradually cooking from the outside to the inside allows the nutrients to be fully preserved, which belongs to Mediterranean diet cooking. Editor's recommendation: magical flax seed, you must know it! Especially middle-aged people, should eat once every few days! ) Black grass seed oil belongs to low-temperature oil. Like evening primrose oil and rose seed oil, it is suitable as conditioning oil for cold salad, salad, pickling and soaking. The vegetables are crispy, and the water content of the oil is moderate, which retains the nutritional essence of fruits and vegetables to the greatest extent. If it is not a dish, drinking a proper amount of nigella seed oil every day can also be used as a health care formula, which is not only anti-inflammatory, but also good for the stomach. If you can't accept the spicy taste of black grass seed oil, such as the traditional formula in the Middle East, you can add honey or drink it with coffee and tea. If the taste is still unacceptable, just apply a small amount of nigella seed oil directly on your face and hands to deeply moisturize your skin, and you will feel the effect of softening keratin in a few days.
