# Remedy/Oils

Def. "liquid fat" or "petroleum-based liquid used as fuel or lubricant" is called an oil.

## Fats

Def. specialized "animal tissue with a high oil content, used for long-term storage of energy" is called fat.
Oils may be animal fats, vegetable oils, or petrochemicals in origin, and may be volatile or non-volatile.
Analysis of black walnut fat content in its oil showed the most prevalent fatty acids are linoleic acid (33.8%), followed (in the same units) by oleic acid (15.3%), linolenic acid (2.7%), palmitic acid (1.9%), and stearic acid (1.5%) (USDA table).
Black walnut kernels are 5% water, 59% fat, 24% protein, and 10% carbohydrates (table). In a 100 gram reference amount providing 619 calories, the kernels supply several dietary minerals in rich content (20% or more of the Daily Value, DV), including manganese (186% DV) and phosphorus (73% DV) among others, and the B vitamins, B6 (45% DV) and pantothenic acid (33% DV) (table). Black walnut kernels are a moderate source of vitamin E (14% DV).

## Essential oils

Def. "a volatile oil, used to make perfumes and flavourings, especially one having the characteristic odour of the plant from which it is obtained" is called an essential oil.
Essential oils are volatile and liquid aroma compounds from natural sources, usually plants. They are not oils in a strict sense, but often share with oils a poor solubility in water. Essential oils often have an odor and are therefore used in food flavoring and perfumery. They are usually prepared by fragrance extraction techniques (such as distillation, cold pressing, or solvent extraction). Essential oils are distinguished from aroma oils (essential oils and aroma compounds in an oily solvent), infusions in a vegetable oil, absolutes, and concretes. Typically, essential oils are highly complex mixtures of often hundreds of individual aroma compounds.
Essential oils of Vitex agnus-cactus have been found in the fruits and in the leaves: the oil of leaves, unripe and ripe fruits differ in compounds, 50 compounds were identified in the oil of unripe fruits, 51 compounds in the oil of ripe fruits and 46 compounds in the oil of the leaves, 1,8-cineole and sabinene are the main monoterpene components and beta-caryophyllene is the major sesquiterpene compound found in the fruits of Vitex agnus-castus.

## Lipids

Def. any "of a group of organic compounds including the fats, oils, waxes, sterols, and triglycerides, characterized by being insoluble in water, and account for most of the fat present in the human body" is called a lipid.
Lipids can be classified by the way that they are made by an organism, their chemical structure and their limited solubility in water compared to oils, have a high carbon and hydrogen content and are considerably lacking in oxygen compared to other organic compounds and minerals; they tend to be relatively nonpolar molecules, but may include both polar and nonpolar regions as in the case of phospholipids and steroids.

## Petroleum

Def. a "flammable liquid ranging in color from clear to very dark brown and black, consisting mainly of hydrocarbons, occurring naturally in deposits under the Earth's surface" is called a petroleum.
Def. "any compound derived from petroleum or natural gas" is called a petrochemical.
Crude oil, or petroleum, and its refined components, collectively termed petrochemicals, originates from ancient fossilized organic materials, such as zooplankton and algae, which geochemical processes convert into oil.
A 42-US-gallon (35 imp gal; 160 L) barrel of crude oil produces approximately 10 US gallons (8.3 imp gal; 38 L) of diesel, 4 US gallons (3.3 imp gal; 15 L) of jet fuel, 19 US gallons (16 imp gal; 72 L) of gasoline, 7 US gallons (5.8 imp gal; 26 L) of other products, 3 US gallons (2.5 imp gal; 11 L) split between heavy fuel oil and liquified petroleum gases, and 2 US gallons (1.7 imp gal; 7.6 L) of heating oil. The total production of a barrel of crude into various products results in an increase to 45 US gallons (37 imp gal; 170 L).
Petrochemicals are the refined components of crude oil

## Cooking oils

Cooking oils are derived either from animal fat, as butter, lard and other types, or plant oils from the olive, corn (maize), sunflowers and many other species.

## Animal oils

Whale oil is preferred for lubricating clocks, because it does not evaporate, leaving dust, although its use was banned in the USA in 1980.
In the 18th and 19th centuries, whale oil was commonly used for lamps, which was replaced with natural gas and then electricity.

### Almond oils

Almonds are a rich source of oil, with 50% of kernel dry mass as fat (whole almond nutrition table). In relation to total dry mass of the kernel, almond oil contains 32% monounsaturated oleic acid (an omega-9 fatty acid), 13% linoleic acid (a polyunsaturated Omega-6 fatty acid|omega-6 essential fatty acid), and 10% saturated fatty acid (mainly as palmitic acid, USDA link in table). Linolenic acid, a polyunsaturated omega-3 fat, is not present (table). Almond oil is a rich source of vitamin E, providing 261% of the Daily Value per 100 ml (table).
When almond oil is analyzed separately and expressed per 100 grams as a reference mass, the oil provides 3,700 kJ (884 kcal) of food energy, 8 grams of saturated fat (81% of which is palmitic acid), 70 grams of oleic acid, and 17 grams of linoleic acid (oil table).
Oleum amygdalae, the fixed oil, is prepared from either sweet or bitter almonds, and is a glyceryl oleate with a slight odour and a nutty taste. It is almost insoluble in ethanol but readily soluble in chloroform or diethyl ether. Almond oil is obtained from the dried kernel of almonds. Sweet almond oil is used as a carrier oil in aromatherapy and cosmetics while bitter almond oil, containing benzaldehyde, is used as a food flavouring and in perfume.

### Annatto oils

Annatto oil is also rich in tocotrienols, beta-carotene, essential oils, saturated and unsaturated fatty acids, flavonoids, and vitamin C.
Bixa orellana is a shrub native to a region between northern South America and Mexico. Bixa orellana is best known as the source of annatto, a natural orange-red condiment (also called achiote or bijol) obtained from the waxy arils that cover its seeds.

### Calendula oils

According to sixteenth-century Englishman John Gerard, every proper soup of Dutch cuisine in his era would include Calendula petals.
The petals are edible and can be used fresh in salads or dried and used to color cheese or as a substitute for saffron. It can be used to add color to soups, stews, poultry dishes, custards and liquors.
The common name for Calendula officinalis in Britain is 'pot-marigold,' named so because of its use in broths and soups.
The petals and pollens of Calendula officinalis contain triterpenoid esters and the carotenoids: flavoxanthin and auroxanthin (antioxidants and the source of the yellow-orange coloration). The leaves and stems contain other carotenoids, mostly lutein (80%), zeaxanthin (5%), and beta-carotene. Plant extracts are also widely used by cosmetics, presumably due to presence of compounds such as saponins, resins, and essential oils.
The flowers of Calendula officinalis contain flavonol glycosides, triterpene oligoglycosides, oleanane-type triterpene glycosides, saponins, and a sesquiterpene glucoside. Calendula flowers are a rich source of lutein, containing 29.8 mg/100g.

### Canola oils

The official definition of canola is "Seeds of the genus Brassica (Brassica napus, Brassica rapa, or Brassica juncea) from which the oil shall contain less than 2% erucic acid in its fatty acid profile and the solid component shall contain less than 30 micromoles of any one or any mixture of 3-butenyl glucosinolate, 4-pentenyl glucosinolate, 2-hydroxy-3 butenyl glucosinolate, and 2-hydroxy- 4-pentenyl glucosinolate per gram of air-dry, oil-free solid."
Rapeseed oil had a distinctive taste and a disagreeable greenish color, due to the presence of chlorophyll and contained a high concentration of erucic acid.
Canola was bred from rapeseed cultivars of B. napus and B. rapa at the University of Manitoba, Canada, having then a different nutritional profile than present-day oil in addition to much less erucic acid. Canola was originally a trademark name of the Rapeseed Association of Canada, and the name was a condensation of "Can" from Canada and "OLA " meaning "Oil, low acid", but is now a generic term for edible varieties of rapeseed oil in North America and Australasia. The change in name serves to distinguish it from natural rapeseed oil, which has much higher erucic acid content.
Canola oil is considered safe for human consumption, and has a relatively low amount of saturated fat, a substantial amount of monounsaturated fat, with roughly a 2:1 mono- to polyunsaturated fats ratio.
"Limited and not conclusive scientific evidence suggests that eating about 1 1/2 tablespoons (19 grams) of canola oil daily may reduce the risk of coronary heart disease due to the unsaturated fat content in canola oil. To achieve this possible benefit, canola oil is to replace a similar amount of saturated fat and not increase the total number of calories you eat in a day. One serving of this product contains [x] grams of canola oil."
There is a substantial reduction in total cholesterol and low-density lipoprotein (LDL) cholesterol, and an increase in tocopherol levels and improved insulin sensitivity, compared with other sources of dietary fat.
Health effects from consuming plant oils rich in alpha-linolenic acid, including canola, stated that there was moderate benefit for lower risk of cardiovascular diseases, bone fractures, and type-2 diabetes.
| Compound | Family | % of total |
| Oleic acid | ω-9 | 61% |
| Linoleic acid | ω-6 | 21% |
| Alpha-linolenic acid | ω-3 | 11% 9% |
| Saturated fatty acids | | 7% |
| Palmitic acid | | 4% |
| Stearic acid | | 2% |
| Trans fat | | 0.4% |
