OIL PULLING


Oil Pulling Sesame oil is one of the few oils recommended for use in oil pulling. Reducing Stress and TensionVarious constituents present in the sesame oil have anti-oxidant and anti-depressant properties. Therefore proponents encourage its use to help fight senile changes and bring about a sense of well being.
Adherents for its therapeutic use reports claims of feeling better than when not using it.
Claims of Being a Panacea
While not approved by the Food and Drug Administration (FDA), sesame oil is reputed to have a number of therapeutic uses.
As with cure-all claims of other folk and therapeutic medicines, it is suggested that regular topical application and/or consumption of sesame oil should mitigate effects of anxiety, nerve and bone disorders, poor circulation, lowered immunity and bowel problems. It is suggested such use would also relieve lethargy, fatigue and insomnia, while promoting strength and vitality, enhancing blood circulation. There are claims that its use has relaxing properties which eases pain and muscle spasm, such as sciatica, dysmenorrhoea, colic, backache and joint pain. There are claims similar to other therapeutic medicines, that its having antioxidants explains beliefs that it slows the ageing process and promotes longevity.
It is suggested that sesame oil, when consumed and/or topically applied, should relieve dryness both externally and internally. Sesame oil is sometimes recommended to alleviate the dryness associated with menopause. It is believed that its use "restores moisture to the skin, keeping it soft, flexible and young looking". It is suggested that it relieves "dryness of joints" and bowels, and eases symptoms of dryness such as irritating coughs, cracking joints and hard stools. Since "dryness of joints" is not a medically classifiable condition, it would be difficult to medically comprehend or verify these claims of panacea.
Other uses include as a laxative, as a remedy for toothaches and gum disease and in the treatment of blurred vision, dizziness, and headaches.
It is suggested that sesame oil could be used in the treatment of dry nose, reduction of cholestrol levels (due to presence of Lignans which are phytoestrogens), anti-bacterial effects, and even slowing down certain types of cancer(due to the anti-oxidant properties of the Lignans).

Coconut oil


Coconut oil, also known as coconut butter, is a tropical oil with many applications. It is extracted from copra (derived from Malayalam word "kopra" which means dried coconut). Coconut oil constitutes seven percent of the total export income of the Philippines, the world's largest exporter of the product.
Coconut oil was developed as a commercial product by merchants in the South Seas and South Asia in the 1860s.

Physical properties
Coconut oil is a fat consisting of about 90% saturated fat. The oil contains predominantly medium chain triglycerides,[1] with roughly 92% saturated fatty acids, 6% monounsaturated fatty acids, and 2% polyunsaturated fatty acids. Of the saturated fatty acids, coconut oil is primarily 44.6% lauric acid, 16.8% myristic acid a 8.2% palmitic acid and 8% caprylic acid, although it contains seven different saturated fatty acids in total. Its only monounsaturated fatty acid is oleic acid while its only polyunsaturated fatty acid is linoleic acid.[2]
Unrefined coconut oil melts at 24-25°C (76°F) and smokes at 170°C (350°F),[3] while refined coconut oil has a higher smoke point of 232°C (450°F).
Among the most stable of all oils, coconut oil is slow to oxidize and thus resistant to rancidity, lasting up to two years due to its high saturated fat content.[citation needed] It is best stored in solid form, below 24.5°C (76°F) in order to extend shelf life.
Dietary consumption issues
Due to the a proportion of saturated fats, regular consumption of coconut oil increases the risk of heart attacks.[4][5] The World Health Organization has determined that reduced consumption of saturated fat, including that from coconut oil, would positively affect health and reduce the prevalence of heart attacks,[6] and epidemiological studies have found that diets high in saturated fatty acids, including lauric, myristic, palmitic, and stearic acid, found in coconut oil, were strong predictors of coronary heart disease risk.[7][8]
Types of oil available
Virgin coconut oil
Virgin coconut oil is derived from fresh coconuts (rather than dried, as in copra). Most oils marketed as "Virgin" are produced one of three ways:
1. Quick drying of fresh coconut meat which is then used to press out the oil.
2. Wet-milling (coconut milk). With this method the oil is extracted from fresh coconut meat without drying first. "Coconut milk" is expressed first by pressing. The oil is then further separated from the water. Methods which can be used to separate the oil from the water include boiling, fermentation, refrigeration, enzymes and mechanical centrifuge.
3. Wet-milling (direct micro expelling). In this process, the oil is extracted from fresh coconut meat after the adjustment of the water content, then the pressing of the coconut flesh results in the direct extraction of free-flowing oil.
Unlike olive oil, there is no world or governing body that sets a standard definition or set of guidelines to classify coconut oil as "virgin". The Philippines has established a Department of Science and Technology (DOST) governmental standard.[citation needed]

Refined oil
Coconuts sundried in Kozhikode, Kerala for making copra, which is used for making coconut oil
Refined coconut oil is referred to in the coconut industry as RBD (refined, bleached, and deodorized) coconut oil. The starting point is "copra", the dried coconut meat. Copra can be made by smoke drying, sun drying, or kiln drying. The unrefined coconut oil extracted from copra (called "crude coconut oil") is not suitable for consumption and must be refined.

Hydrogenated oil
Hydrogenated coconut oil may either be fully or partially hydrogenated. This happens mostly in tropical climates, since the natural melting point of coconut oil is about 76 degrees F, and already naturally a solid in most colder climates.

Fractionated oil
"Fractionated coconut oil" is a fraction of the whole oil, in which most of the long-chain triglycerides are removed so that only saturated fats remain. It may also referred to as "caprylic/capric triglyceride" or medium-chain triglyceride (MCT) oil because mostly the medium-chain triglycerides caprylic and capric acid are left in the oil.
Because it is completely saturated, fractionated oil is even more heat stable than other forms of coconut oil and has a nearly indefinite shelf life.[citation needed]
Applications

Cooking
Coconut oil is commonly used in cooking, especially when frying, and it has a high smoke point which makes it good for this purpose. In communities where coconut oil is widely used in cooking, the refined oil is the one most commonly used.
Coconut oil is often used in making a curry or in popcorn machines at movie theaters.
Manufacturing
Coconut oil is used in volume quantities for making margarine, soap and cosmetics.
Hydrogenated or partially-hydrogenated coconut oil is often used in non-dairy creamers, and snack foods.
Fractionated coconut oil is also used in the manufacture of essences, massage oils and cosmetics
Coconut oil is an important component of many industrial lubricants, for example in the cold rolling of steel strip.
Cosmetics and skin treatments
Coconut oil is excellent as a skin moisturiser and softener. A study shows that extra virgin coconut oil is as effective and safe as mineral oil when used as a moisturiser, with absence of adverse reactions.[9] Although not suitable for use with condoms, coconut oil is an excellent, inexpensive lubricant for sexual intercourse[10], though it may cause an allergic reaction.
In India and Sri Lanka, coconut oil is commonly used for styling hair, and cooling or soothing the head. People of Tamil Nadu and other coastal areas such as Kerala, Karnataka, Maharashtra and Goa bathe in warm water after applying coconut oil all over the body and leaving it as is for an hour to keep body, skin, and hair healthy.

USES OF SESAME OIL

น้ำมันงา - Uses of Sesame Oil
Uses of Sesame Oil
Sesame oil's popularity in Asia (particularly in South Indian state of Tamil Nadu) can be likened to olive oil's popularity in the mediterranean. Its main uses are
1. Cooking. Sesame oil carries a premium relative to other cooking oils and is considered more stable than most vegetable oils due to antioxidants in the oil. Sesame oil is least prone, among cooking oils, to turn rancid. This is because it has a very high boiling point. In effect, sesame oil retains its natural structure and doesn't break down even when heated to a very high temperature. Also it has a good reputation for being safe to the heart just like Olive oil and Sun Flower oil. Because of this, it is ideally suited for deep frying.
2. Body Massage. Sesame oil is reputed for its ability to penetrate the skin easily, nourishing and detoxifying even the deepest tissue layers. Sesame oil is immensely popular in India where its used in oil massage. It is ideal oil for people in the hot tropics to cool down. It is recommended to apply the oil on the parts of the body which generate most heat, like navel, head, eyebrows, foot tips etc. and let the body soak the oil for an hour or so and then bathe in warm water which will help to open the pores further. Caution oil massage should not be attempted when ill or suffering from cold. It may worsen the symptoms before giving relief, if any.
3. Hair Oil. Applying Sesame oil for the hair is believed to result in darker hair.
Medicinal Uses
Research into the health effects of sesame oil is beginning to emerge.
High percentage of polyunsaturated fatty acids.
"Sesame oil is unique in that, it has the highest concentrations of omega-6 fatty acids. At the same time, the oil contains two natural-occurring preservatives, sesamol and sesamin. As a result, sesame oil is the only oil which has a high percentage of polyunsaturates and also keeps at room temperature. (Olive oil also keeps at room temperature, but it is predominately composed of the omega-9 monounsaturated oil.)"
The presence of high levels of Polyunsaturated fatty acids might help in controlling blood pressure. It can be used in cooking in place of other edible oils and may help reduce high blood pressure and lower the amount of medication needed to control hypertension.
"The effect of the oil on blood pressure may be due to polyunsaturated fatty acids (PUFA), and the compound sesamin – a lignan present in sesame oil. Both compounds have been shown to reduce blood pressure in hypertensive rats. Sesame lignans also inhibit the synthesis and absorption of cholesterol in these rats."
Vitamins and Minerals Sesame oil is a good source of Vitamin E. Vitamin E is an anti-oxidant which means it helps lower cholesterol. Sesame oil also contains magnesium, copper, calcium, iron and vitamin B6.Oil Pulling Sesame oil is one of the few oils recommended for use in oil pulling. (sunflower oil is the other oil recommended).
Reducing Stress and Tension Various constituents present in the sesame oil have anti-oxidant and anti-depressant properties, which help to fight senile changes and bring about a sense of well being."People with high Stress and Tension can be prone to anxiety, nerve and bone disorders, poor circulation, lowered immunity and bowel problems such as wind, constipation and irritable bowel. They tend towards excess dryness both externally and internally. Used regularly, sesame oil is wonderful for reducing stress and tension, nourishing the nervous system and preventing nervous disorders, relieving fatigue and insomnia, and promoting strength and vitality. Those patients who use sesame oil daily have reported feeling stronger, more resilient to stress, with increased energy and better resistance to infection. Its rejuvenating properties certainly do revitalize those feeling tired and run down, while its warming effects enhance the circulation. Its relaxing properties ease pain and muscle spasm, such as sciatica, dysmenorrhoea, colic, backache and joint pain. The antioxidants explain its reputation for slowing the ageing process and increasing longevity, and certainly regular oiling of the skin restores moisture to the skin, keeping it soft, flexible and young looking. It also lubricates the body internally, particularly the joints and bowels, and eases symptoms of dryness such as irritating coughs, cracking joints and hard stools."
Other uses include as a laxative, as a remedy for toothaches and gum disease and in the treatment of blurred vision, dizziness, and headaches.
Other Research findings support Sesame oil's use in the treatment of dry nose, reduction of cholestrol levels (due to presence of Lignans which are phytoestrogens), anti-bacterial effects, and even slowing down certain types of cancer. (again because of the anti-oxidant properties of the Lignans)
