How do you extract oil from herbs (thyme, specifically)?

different ways to do it.  steam distillation, expression, solvent extraction and efleurage. the first is the easiest and what you want to know if you are looking for a how to. Use hot steam, like a steamer, you'll end up with the oil and water.  then separate the oil.  \n\nthe other methods are more complicated, but you do end up with more oil.  but at what price?  second method the is to use pressure or centrifugation. At home, not likely you have anything to make this work.   The third method you use a solvent, but then the oil and solvent are mixed.  You then evaporate the solvent (you can get at a whole foods store to do this) when the solvent is evaporated you are left with a heavy, waxy substance called concrete. Then you have to separate the liquid from the was.  it's great because it is most concentrated from of aroma, but very time consuming and complicated.  That last, efleurage is a really long process using animal fats and alcohol. Although essential oils main usage is in cosmetics and perfumery, many of them do have proved therapeutic properties.

Try tea tree oil. You can find it at any health food store. I use it straight from the bottle. It works wonders.

The 1 oz. of mixed herbs in the following recipe is non-specified because I have no idea what your hair is like - oily/dry, dark/light, etc. For more specific herbs, email me.\n\nGeneral Shampoo Recipe:\nMakes 8 oz.\n\nPut 1 oz or more of mixed herbs in a nonmetal or enamel pot and add 10 ozs. or a bit more of spring water - or tap water will do. \nBring gently to a boil, lower heat, and gently simmer for 5-10 mins.\nTurn off heat & let infuse for 5-10 minutes longer. Strain off the liquid into another pot that contains 1 oz. of good quality Olive oil castile soap. Stir until the soap melts and add 1 or 2 drops of your favorite essential oil. \n\nNow bottle your genuine herbal shampoo, use sparingly and it will last 1 person from 3-8 weeks.\n\nI have many more recipes at my website.\n\nA good shampoo should contain:\na medicinal or cleansing herb\nan emollient\nan herb for color\nan herb for conditioning\nscent, if you like

If the rest of your question is: "... kill staph." \n\nThen, I would have to ask if you can test with only one herb, or if you can use an herbal compound.\n\nIf using compounds is acceptable, I suggest a sufficiently strong mixture of:  White Thyme, Tea Tree Oil, Lemon, and Oregano.\n\nIf you just grab these items off the shelf, it's not likely that you'll experience great success at killing the Staph. \n\nRather, use pure essential oils, which are a highly concentrated, water distilled version of the herbs/juice.  There is no alcohol present in pure essential oils, so the success you experience will truly be from the property of the herbs.

If you're Allergic to parsley, stay away and don't eat it!\nalso: parley camphor(volatile oils) maybe toxic in large quantities: examples: Blood pressure, pulse rates, muscle weakness, paralysis, lung congestion, swelling of the liver, diuretic, irriate kidneys

You can steam your face over a bowl of hot water, you can use witch hazel which absorbs the oil, or try using lemon juice.

I'm guessing you are asking how to make BIODIESEL from vegetable oil. Here is my answer to that:\n\nThe process is quite simple. Alchohol and vegetable oil or some other similar fat are mixed with the catalyst. It can be used animal fats or vegetable oils. The alchohol can be methanol or ethanol. Methanol is generally cheaper since it is made in industrial quantities from petroleum. Sodium hydroxide (aka lye or caustic soda) or potassium hydroxide are mixed in as the catalyst.\n\n1. Methanol and sodium hydroxide are combined making sodium methoxide.\n2. Sodium methoxide is mixed and stirred with vegetable oil (trigycerides). The oil molecules break apart and this produces methylesters and glycerol. The glycerol and catalyst will settle to the bottom as they are both denser than the methylesters. The methylester is drained off after the reaction is complete, about 8 hours.\n3. The methylester (biodiesel) is washed by mixing it with water. The water dissolves any traces of the catalyst and the alchohol. After settling for a few days the water can be drained from the bottom of the tank.\nThe glycerol can be filtered and purified as well. It can be burnt as fuel, or it makes a powerful degreaser (it is already almost soap) and can be made into high quality soap.\n\n*******************************************************\nIf your question is actually how to REFINE CRUDE VEGETABLE OIL into refined vegetable oil, then here are the steps:\n1. Oil extraction from seeds using pressing, solvents, or both (e.g. high quality virgin olive oil is pressed, while lower quality pomace uses solvents to extract)\n2. oil refiining: the crude vegetable oil is mixed with sodium hydroxide which removes the free fatty acids by forming soap\n3. bleaching: this removes pigments by adding a 'bleaching clay' and then filtering the clay\n4. deoderization: this removes volatile compounds and is often done by heating and distillation\n5. fractional crystallization: this is separation of solid fats by allowing the oil to solidify at cooler temperautes\n6. winterization: often some oils must have the fats which solidfy at low room temperatures removed. The oil is cooled and the solids filtered out. \n7. hydrogenation: this binds hydrogen to the unsaturated fatty acids and prevents later oxidation and can be used to make the oil solid\n8. texturing: this is a process where cooled fats are whipped to add some air and improve the texture and appearance, used for shortening\nhttp://www.markets.duke.edu/student_it/soc142_spring2002/team4/sustaining.html

The method we use to practice at home for making coconut oil is - first select mature coconuts fresh or dried. Then remove the outermost cover including the fibrous part. Split the coconut into halves and let it dry in bright sun. The process of drying continues until the moisture in the coconut flesh disappears and also the coconut gets separated from the shell by it self.Once the coconuts are completely dried they are chopped to small pieces and grinded to extract oil. The extracted oil is then collected after filtration. Also the remainings of the coconut  after extraction is used as a food for the cattle.

This is usually done by distilling in which you need to use some sort of solvent. Steam distillation is also used where you end with crystals after fast cooling.\n\n Here is a great site that explains alot.\nhttp://www.wsu.edu/~gmhyde/433_web_pages/433Oil-web-pages/essence/essence-oils.html\n\nIt would depend on what you were using the  oil for. You could simply heat it in a bit of water creating a drink or use an oil and make a paste.

No, there isn't.\n\nAll other responses are bullsh1t.  But feel free to waste your money buying some crappy herbs which do nothing.
