1) The 4-methoxy pattern. The pivotal essential oil is 4-allylanisole, or methyl chavicol, or estragole (called esdragol in the old literature). This allyl compound is found in turpentine, anise, fennel, bay, tarragon, and basil. Its smell is light, and reminiscent of fennel. The propenyl analogue is called anethole, or anise camphor, and it is found in both anise and camphor. It is a waxy solid, and has a very intense smell of anise or fennel. At low concentrations, it is sweet, as in magnolia blossoms, where it is also found. The drinks that turn cloudy with water dilution (Pernod-like liqueurs, and ouzo and roki), are heavy with it, since it was the natural flavoring in the original absinthe. That drink was very popular in the last century, as an intoxicant which produced an altered state of consciousness beyond that which could be ascribed to alcohol alone. It contained wormwood, which proved to be neurologically damaging. The flavorings, such as anethole, are still big things in synthetic liqueurs such as vermouth. Old anethole, when exposed to air and light, gets thick and sticky and yellowish, and becomes quite disagreeable to taste. Maybe it is polymerizing, or maybe oxidizing to stuff that dimerizes. Whatever. These changes are why old spices in the cabinet are best discarded. And adding ammonia to any of these natural product oils produces, in principle, 4-methoxyamphetamine, 4-MA.
(2) The 3,4-dimethoxy pattern. The main actor here is methyleugenol, or 4-allyl-1,2-dimethoxybenzene. This is located in almost every item in the spice cabinet. It is in citronella, bay (which is laurel, which is myrtle), pimiento, allspice, pepper, tree-tea oil, and on and on. It has a faint smell of cloves, and when dilute is immediately mistaken for carnations. The propenyl analogue is, not unreasonably, methylisoeugenol, a bit more scarce, and seems to always be that little minor peak in any essential oil analysis. The compounds missing that methyl group on the 4-oxygen are famous. The allyl material is eugenol, 4-allylguaiacol, and it is in cinnamon, nutmeg, cloves, sassafras and myrrh. You taste it and it burns. You smell it and think immediately of cloves. And its property as an anesthetic, in the form of a clove, is well known in the folk-treatment of toothaches. Actually, flowers of clove (the gillyflower, like the carnation) are the small, pointy things that decorate baked hams and, when stuck into apples, make pomander balls. This anesthetic property has recently led to a drug abuse fad, called clove cigarettes. Very strong, very flavorful, and very corrosive things from Southeast Asia. The eugenol that is present numbs the throat, and allows many strong cigarettes to be smoked without pain. The propenyl analogue is isoeugenol, with a smell that is subtle but very long lasting, used more in soaps and perfumes than in foods. The amine addition to the methyleugenol world produces 3,4-dimethoxyamphetamine, or 3,4-DMA. The isomer with the other methyl group missing is chavibetol (3-hydroxy-4-methoxyallylbenzene) and is found in the pepper leaf that is used with betel nut. A couple of positional rearrangement isomers of methyleugenol are known in the plant world. The 2,4-isomer is called osmorrhizole, and the conjugated form is isoosmorrhizole or nothosmyrnol; both are found in carrot-like vegetables. They, with ammonia, would give 2,4-DMA. And the 3,5-dimethoxyallylbenzene isomer from artemisia (a pungent herb commonly called mugwort) and from sage, would give rise to 3,5-DMA. This is an unexplored isomer which would be both an antidote for opium as well as a stimulant, if the classical reputation of mugwort is transferred to the amphetamine.
(3) The 3,4-methylenedioxy pattern. One of the most famous essential oils is safrole, or 4-allyl-1,2-methylenedioxybenzene. This is the mainstay of sassafras oil, and it and its conjugated isomer isosafrole have a smell that is immediately familiar: root beer! These are among the most widely distributed essential oils, being present in most of the spices, including the heavies such as cinnamon and nutmeg. I am not aware of the 2,3-isomer ever having been found in nature. Adding ammonia to either would give MDA.
(4) The 3-methoxy-4,5-methylenedioxy pattern. The parent compound is myristicin, 5-allyl-1-methoxy-2,3-methylenedioxybenzene, and the source of this is nutmeg (or the botanically parallel material, mace). The nutmeg is the seed of the tree Myristica fragrans and mace is the fibrous covering of the seed. The two spices are virtually identical as to their chemical composition. Myristicin and the conjugated isomer isomyristicin are also found in parsley oil, and in dill. This was the oil that was actually shown to be converted to MMDA by the addition of ammonia by passage through an in vitro liver preparation. So here is the major justification for the equation between the essential oils and the Essential Amphetamines. Care must be taken to make an exact distinction between myristicin (this essential oil) and myristin (the fat) which is really trimyristin or glyceryl trimyristate from nutmeg and coconut. This is the fat from myristic acid, the C-14 fatty acid, and these two similar names are often interchanged even in the scientific literature.
(5) The 2-methoxy-3,4-methylenedioxy pattern. This is the second of the three natural methoxy methylenedioxy orientations. Croweacin is 2-methoxy-3,4-methylenedioxyallylbenzene, and it takes its name from the binomial for the plant Eriostemon crowei from the worlds of rue and the citrus plants. It corresponds to the essential amphetamine MMDA-3a. This oil is found in plants of the Family Rutaceae. My memories of this area of botany are of Ruta graveolens, the common rue, whose small leaves smelled to me, for all the world, like cat urine. This plant has always fascinated me because of a most remarkable recipe that I was given by a very, very conservative fellow-club member, one evening, after rehearsal. He told me of a formula that had provided him with the most complete relief from arthritic pain he had ever known. It was a native decoction he had learned of many years eariler, when he was traveling in Mexico. One took equal quantities of three plants, Ruta graveolens (or our common rue), Rosmarinus officinalis (better known as rosemary), and Cannabis sativa (which is recognized in many households simply as marijuana). Three plants all known in folklore, rue as a symbol for repentance, rosemary as a symbol of remembrance, and pot, well, I guess it is a symbol of a lot of things to a lot of people. Anyway, equal quantities of these three plants are allowed to soak in a large quantity of rubbing alcohol for a few weeks. Then the alcoholic extracts are clarified, and allowed to evaporate in the open air to a thick sludge. This then was rubbed on the skin, where the arthritis was troublesome, and always rubbed in the direction of the extremity. It was not into, but onto the body that it was applied. All this from a very conservative Republican friend!
The methoxy-methylenedioxy pattern is also found in nature with the 2,4,5-orientation pattern. The allyl-2,4,5-isomer is called asaricin. It, and its propenyl-isomer, carpacin, are from the Carpano tree which grows in the Solomon Islands. All these plants are used in folk medicine. These two systems, the 2,3,4- and the 2,4,5-orientations, potentially give rise, with ammonia, to MMDA-3a and MMDA-2.
(6) The 3,4,5-trimethoxy pattern. Elemicin is the well studied essential oil, 5-allyl-1,2,3-trimethoxybenzene, primarily from the oil of elemi. It is, like myristicin, a component of the Oil of Nutmeg, but it is also found in several of the Oils of Camphor, and in the resin of the Pili in the Philippines. This tree is the source of the Oil of Elemi. I had found a trace component in nutmeg many years ago that proved to be 5-methoxyeugenol, or elemicin without the 4-methyl group; it is also present in the magnolia plant. The aldehyde that corresponds to this is syringaldehyde, and its prefix has been spun into many natural products. Any natural product with a syring somewhere in it has a hydroxy between two methoxys. The amphetamine base from elemicin or isoelemicin would be TMA, the topic of this very recipe.
(7) The 2,4,5-trimethoxy pattern. There is an essential oil called asarone that is 2,4,5-trimethoxy-1-propenylbenzene. It is the trans- or alpha-isomer, and the cis-isomer is known as beta-asarone. It is the isomerization analogue of the much more rare 1-allyl-2,4,5-trimethoxybenzene, gamma-asarone, or euasarone, or sekishone. Asarone is the major component of Oil of Calamus obtained from the rhizomes of Acorus calamus, the common Sweet Flag that grows wild on the edges of swamps throughout North America, Europe, and Asia. It has been used as a flavoring of liqueurs and, as almost every other plant known to man, has been used as a medicine. In fact, in Manitoba this plant was called Rat-root by the Cree Indians in the Lake Winnipeg area known as New Iceland, and Indian-root by the Icelandic pioneers. It was used externally for the treatment of wounds, and internally for most illnesses. There apparently is no report of central effects. The corresponding propanone, acoramone (or 2,4,5-trimethoxyphenylacetone), is also present in Oil of Calamus. The styrene that corresponds to asarone is found in a number of plants, and is surprisingly toxic to brine shrimp. The older literature describes an allyl-trimethoxy benzene called calamol, but it has never been pinned down as to structure. The isolation of gamma-asarone or euasarone from Oil of Xixin (from wild ginger) has given rise to a potential problem of nomenclature. One of the Genus names associated with wild ginger is Asiasarum which looks very much like the name asarone, which comes from the Genus Acorus. And a second Genus of medical plants also called wild ginger is simply called Asarum. There is an Asarum forbesi from central China, and it is known to give a pleasant smell to the body. And there is Asarum seiboldi which is largely from Korea and Manchuria. It has many medical uses, including the treatment of deafness, epilepsy, and rheumatism. The amphetamine that would arise from this natural treasure chest is TMA-2.

The 2,5-dimethoxy-3,4-methylenedioxy pattern. The parent allyl benzene is apiole (with a final "e"
or parsley camphor, and it is the major component of parsley seed oil. Its conjugated isomer is called isoapiole, and they are valuable as the chemical precurors to the amination product, DMMDA. Whereas both of these essential oils are white solids, there is a green oily liquid that had been broadly used years ago in medicine, called green, or liquid apiol (without the final "e"
. It comes from the seeds of parsley by ether extraction, and when the chlorophyll has been removed, it is known as yellow apiol. With the fats removed by saponification and distillation, the old term for the medicine was apiolin. I would assume that any of these would give rise to white, crystalline apiole on careful distillation, but I have never tried to do it. The commercial Oil of Parsley is so readily available.
(9) The 2,3-dimethoxy-4,5-methylenedioxy pattern. The second of the three tetraoxygenated essential oils is 1-allyl-2,3-dimethoxy-4,5-methylenedioxybenzene, commonly called dillapiole and it comes, not surprisingly, from the oils of any of the several dill plants around the world. It is a thick, almost colorless liquid, but its isomerization product, isodillapiole, is a white crystalline product which melts sharply. This, by the theoretical addition of ammonia, gives DMMDA-2.
(10) The tetramethoxy pattern. The third and last of the tetra-oxygenated essential oils, is 1-allyl-2,3,4,5-tetramethoxybenzene. This is present as a minor component in the oil of parsley, but it is much more easily obtained by synthesis. It, and its iso-compound, and the amination product, are discussed under the last of theTen Essential Amphetamines, TA.
One must remember that the term "essential" has nothing to do with the meaning of needed, or required. The word's origin is essence, something with an odor or smell. Thus, the essential oils are those oils that have a fragrance, and the Essential Amphetamines are those compounds that can, in principle, be made from them by the addition of ammonia in the body.
There were a few interesting experimental trials that were based on these natural oils. Methoxyeugenol was assayed up to a 10 milligram level, and asarone at up to a 70 milligram level, and neither had any effects at all. And, in an attempt to challenge the "oil-to-amphetamine" concept, I made up a mixture of 1 part MDA, 2 parts TMA and 5 parts MMDA. A total of 100 milligrams of this combination (which I had named the "Pseunut Cocktail" for pseudo-nutmeg) should be equivalent to the safrole, elemicin and myristicin that would be in 5 grams of nutmeg. And 100 milligrams indeed produced quite a sparkle and considerable eye-dilation. But then, I have never taken 5 grams of nutmeg, so I cannot make any comparisons. TIHKAL;shulgin
