Description

USE OF AN HERBAL FORMULATION CONTAINING LINSEED OIL IN THE TREATMENT OF REGULATING SOME BLOOD LIPID (FAT) LEVELS

TECHNICAL FIELD

The present invention relates to use of an herbal formulation containing linseed oil (Oleum Lini) in the drug industry in the chemical industry.

In particular, the invention relates to use of an herbal formulation that is prepared with linseed oil being rich in alpha-linolenic acid which is an herbal fatty acid containing Omega 3; that is in the form of a capsule having an antioxidant property, in the regulation of some blood lipid (fat) levels.

STATE OF THE ART

Omega 3 is an essential fatty acid, it is a fatty acid that should be taken from outside to maintain the organism's life as other essential fatty acids and that cannot be synthesised in body. This essential fatty acid should be taken by means of nutrition and supplements into body. ALA that is an herbal fatty acid containing Omega 3 taken from outside into organism can be used as a herbal Omega 3 (ALA) source in those, particularly in vegetarians who cannot use fish oil and functions as an adjuvant in regulating some blood lipid (fat) levels, treatment of chronic constipation, treatment of cardiovascular system disease and mild gastrointestinal discomfort.

In the state of art; synthetic substances or chemical agents in certain amounts can be found in the products that is used as an adjuvant to the treatment of regulating blood lipid (fat) levels. Use of synthetic and chemicals substances may badly affect the various systems of the body by causing various side effects in the organism.

Further, the products in most of the embodiments are in a liquid form. This complicates the administration of controlled dosing. Therefore, essential dosing cannot be achieved exactly and precisely.

In the literature, one of the patents pertaining to this matter is the application numbered CN103099755. The invention mentions a shower foam prepared with various herbal materials including linseed that is natural and providing vitality and softness to skin. The application numbered CN105560646 mentions a herbal mixture comprising nanking cherry, tamarind, banana, dragon's tongue leaf, carageen, Russian bochniakia plant, Japanese dok roots, Nepal dok roots, radix Scrophulariae, radix lithospemi, coffee bean, senna, unripe Inula, orange, pakchoi plantlets, alopecia, senna and peach flowers as well as linseed so as to treat the symptoms such as constipation, irregular bowel movements, hard stool and pellet-like dry stool.

As a result, due to the aforementioned drawbacks and insufficiency of the existing solutions regarding the subject matter, the need for a development in the technical field related to the regulation of some blood lipid (fat) levels has arisen.

OBJECTS OF THE INVENTION Main object of the invention is to be able to use linseed oil formulation in order to regulate some blood lipid (fat) levels.

The formulation comprises Omega 3, highly olinolenic acid (ALA, 18:3n-3) and lignans. Linseed oil causes serum total cholesterol levels to decrease by 15 percent. Use of linseed oil containing highly ALA decreases serum total cholesterol, LDL (low density lipoprotein) levels on people with hyperlipidaemia. Further, LDL cholesterol levels are decreased on postmenopausal women. This effect is resulted from SDG (secoisolariciresional diglucoside) composition being precursor of lignans named as enterodiol and enterolactone that is in breasts isolated from linseed, and 33 percent decrease in serum total cholesterol and 73 percent decrease in plaque have been observed. These effects of linseed oil clarify the effects inhibiting the development of atherosclerosis and the effects regulating the blood lipid levels. Thus, the formulation can be used as adjuvant to the regulation of blood lipid (fat) levels.

The formulation may assist in decreasing thrombosis incidence since it has the antithrombotic effects and the effects reducing aggregation of thrombosis. Therefore, the formulation can be used as adjuvant in the treatment of cardiovascular diseases.

Another object of the invention is to provide a formulation containing no chemical substances, and being totally natural and herbal. No heat or chemical treatment is carried out even when the linseed oil used in the content of the formulation is obtained. Thus, active substances, nutritional values, vitamin and minerals in the plant are directly infused into the product without losing them. Another object of the invention is to ensure to minimise the side effects badly affecting the human health by means of the content formed without chemicals. The side effects affecting only gastro-entero system such as nausea, vomit, diarrhea resulting from the use of totally natural and herbal products is rarely observed.

Further object of the invention is to provide ease of use in terms of patient compliance through the fact that the formed formulation is in the form of capsule. Furthermore, it is advantageous in administrating the dosing in said indications by means of the formed capsule form. DETAILED DESCRIPTION OF THE INVENTION

Preferred use of an herbal capsule formulation obtained by means of linseed oil so as to achieve the object of the invention is described solely for a better understanding of the subject without generating any restrictive effect.

Linseed Oil:

There are oil and lignans being rich in omega-3(ALA) in the linseed. Linseed among the oils obtained through seeds comes into prominence because it has highly olinolenic acid (ALA, 18:3n-3) and lignans. Linseed comprises oil rate of 35-45 percent whose ALA rate is varying between 45-52 percent thereof. ALA is classified as Omega 3 group of fatty acids.

Linseed oil exhibits various pharmacological effects due to ALA in its structure. Linseed oil causes serum total cholesterol levels to decrease by 15 percent. Use of linseed oil containing highly ALA decreases serum total cholesterol, LDL (low density lipoprotein) levels on people with hyperlipidaemia. Further, LDL cholesterol levels are decreased on postmenopausal women. This effect is resulted from SDG (secoisolariciresional diglucoside) composition being precursor of lignans named as enterodiol and enterolactone that is in breasts isolated from linseed, and 33 percent decrease in serum total cholesterol and 73 percent decrease in plaque have been observed. These effects of linseed oil clarify the effects inhibiting the development of atherosclerosis and the effects regulating the blood lipid levels. Thus, the formulation can be used as adjuvant to the regulation of blood lipid (fat) levels.

The formulation may assist in decreasing thrombosis incidence since it has the antithrombotic effects and the effects reducing aggregation of thrombosis Therefore, the formulation can be used as adjuvant in the treatment of cardiovascular diseases. Linseed oil exhibits antioxidant effects due to ALA therein. Furthermore, ALA has suppressor effects on interleukin, TNF (Tumor necrosis factor), leukotriene B4 and polymorphonuclear leukocytes. These facts can explain the effects of linseed oil that can inhibit the development of inflammation. it is known that linseed oil can increase calcium absorption. Along with the effect, it has supportive effects on bone health.

The linseed oil not only is a good nutritional source but also improve bowel movement in adults due to fibrous structure therein. Defecation frequency and continuity are regulated on those who uses the linseed oil. Therefore, the formulation can be used as adjuvant to the treatment of chronic constipation and mild gastrointestinal problems.

The linseed oil is important for adults who cannot use fish oil, particularly vegetarians within the scope of the fact that it is supportive in terms of herbal Omega 3.

Content of capsule formulation:

Linseed oil as active substance and dl a-tocopherol, dl a-tocopheril acetate, glycerine, purified water and gelatine as inactive substance are employed in the formulation, dl α-tocopherol and a-tocopheril acetate serve as preservative substance, dl α-tocopherol and dl a-tocopheril acetate are added into the formulation in the ratio of ppm.

Production method of the capsule:

Production steps of capsule formulation follows as below: linseed oil, one of the raw materials, is subjected to sieving process. After sieving process, if necessary, breaking process is carried out. After carrying out said process and obtained desired size, the linseed oil is sent to cold pressing unit. By means of cold pressing method, extraction of oil from raw material is performed. In said method, it is not exceeded over 55 °C. The oil obtained through cold pressing unit is held in the mixing and settling tanks before filtering process. Thus, possible particles can be easily separated by means of mixing and settling processes. the extracted oil is fed to the filter unit indoor and at room temperature after mixing and settling tanks. Particles in the oil are filtered in the filter unit if there are. After filtering process, dl o tocopherol and dl otocopheril acetate as preservative substance are added into the obtained oil. Thus, the mixture of which content is formed, is obtained.

On the other hand, the gelatine is prepared in the gelatine preparing unit so as to maintain the integrity of capsule while carrying out these processes.

After forming the mixture and preparing the gelatine, capsules in desired dosages are prepared by means of sending it to capsule producing unit. Said capsules are gelatine capsules.

After prepared the capsule, drying process is carried out. Dried capsules are packaged. Instruction of Use of Capsule:
