Best Essential Oils for Beginners (2026)
Why "Aromatherapy" Is a 20th-Century Word for an Ancient Practice
The word "aromatherapy" is barely ninety years old, yet the practices it describes stretch back more than four thousand years. Humans have burned resins, steeped herbs in oils, and inhaled fragrant smoke in ritual and daily life since before written records began. What changed in the twentieth century was not the behavior itself but the attempt to systematize it — to strip away the spiritual scaffolding, examine the chemistry, and decide what, if anything, the aromatic compounds in plants actually do to a living body.
That project is still underway. Modern researchers are publishing peer-reviewed studies on lavender and anxiety, frankincense and inflammation, while at the same time multi-level marketing companies are selling the same oils with claims that would make a pharmacologist wince. Understanding the history of aromatherapy does not resolve that tension, but it does make it legible. The gap between what ancient Egyptians believed about Frankincense and what a 2024 randomized controlled trial can demonstrate is enormous — and bridging it honestly requires knowing how we got from one to the other.
Ancient Egypt: Kyphi, Mummification, and Temple Incense
Egypt is the starting point for most histories of aromatherapy, and with good reason. The Egyptians left behind hieroglyphic texts, wall paintings, and physical artifacts that document an extraordinarily sophisticated relationship with aromatic plants. The Ebers Papyrus, dated to roughly 1550 BCE but believed to copy earlier sources, contains hundreds of preparations involving resins, aromatic woods, and plant extracts. Many were applied topically; others were burned as incense or used in ritual fumigation.
The compound most closely associated with Egyptian ceremony is kyphi, a blended incense whose exact recipe varies across sources but consistently includes Myrrh, calamus, juniper, and honey-soaked raisins among its ingredients. Greek and Roman writers later described kyphi as having calming properties, and Plutarch wrote that it was burned in temples at sunset to ease the transition into evening. Whether kyphi was a religious offering, a fumigant, a medicine, or all three simultaneously is a distinction the Egyptians themselves may not have drawn.
Myrrh and Frankincense appear constantly in Egyptian texts, both as ritual offerings and as preservative agents in the embalming process. Egyptian embalmers used a range of aromatic resins to inhibit decomposition and impart fragrance to the body — a practice that later drew the attention of scientists studying the antimicrobial properties of these same compounds. Cedar, cinnamon, and cassia were imported from Lebanon, India, and the Horn of Africa at considerable expense, indicating how highly the Egyptians valued these materials.
It is important to note that what the Egyptians were doing was not distillation in the modern sense. They extracted aromatic compounds through infusion, enfleurage, and pressing rather than steam distillation. The oils they worked with were aromatic plant materials steeped or pressed into animal or vegetable fats — effective carriers, but chemically distinct from the concentrated essential oils that would come later.
India and the Ayurvedic Tradition
Parallel to Egypt, the Indian subcontinent developed its own elaborate system of aromatic medicine within the broader framework of Ayurveda, the traditional system of medicine whose foundational texts — the Charaka Samhita and the Sushruta Samhita — are estimated to date from between 600 BCE and 600 CE, though they draw on still older oral traditions.
Ayurvedic practice made extensive use of Sandalwood, vetiver, turmeric, ginger, and dozens of other aromatic plants. These materials were understood within the Ayurvedic framework of doshas — the constitutional types that govern health and imbalance — rather than in terms of isolated chemical constituents. Aromatics were burned, applied in massage oils, and incorporated into complex herbal preparations. The concept of Abhyanga, the Ayurvedic full-body oil massage, often incorporated infused oils as both a therapeutic and a preventive practice.
India may also have an early claim to distillation technology. Archaeological evidence from the Indus Valley civilization, including terracotta distillation vessels dating to roughly 3000 BCE, has been cited in some academic literature as evidence of early aromatic extraction, though the interpretation of these artifacts remains debated among historians of science.
Traditional Chinese Medicine
Chinese engagement with aromatic plants is documented in the Shennong Bencao Jing (the Divine Farmer's Classic of Materia Medica), traditionally attributed to the legendary emperor Shennong and believed to have been compiled somewhere between the first and third centuries CE. The text catalogs hundreds of plant materials, many of them aromatic, and organizes them by their proposed effects within the framework of Chinese medicine — a system built around qi, yin and yang, and the five elements rather than biochemical mechanism.
Fragrant woods, resins, and herbs occupied an important place in Chinese medicine and ritual throughout the imperial period. Incense burning was both a spiritual practice and a way of purifying space. Aromatic fumigation was used in efforts to ward off disease, a logic that would not have seemed foreign to European plague doctors centuries later.
Greek and Roman Physicians: Hippocrates and Dioscorides
Greek medicine began to disentangle the therapeutic from the religious more explicitly than its predecessors. Hippocrates, writing in the fifth century BCE, advocated aromatic baths and massage with infused oils as part of a broader regimen of hygiene and health maintenance. His writings do not frame these practices in supernatural terms but in observations about the body's responses — a notable early step toward naturalistic medicine.
The most important classical source on plant medicine is Pedanius Dioscorides, a Greek physician who served with the Roman army in the first century CE and compiled De Materia Medica, a five-volume work cataloging roughly six hundred plants and their uses. Dioscorides described aromatic plants including Myrrh, rose, and cedar in detail, and his work remained the dominant European reference on medicinal plants for more than fifteen hundred years — a remarkable run that speaks to both the quality of his observations and the relative stagnation of European botany in the centuries that followed.
The Romans absorbed Greek medical knowledge and expanded the trade networks that brought aromatic materials from across the known world into Mediterranean markets. Roman bathing culture, which paired aromatic oils with elaborate public bath complexes, spread the practical use of fragrant plant materials across a vast geography.
The Islamic Golden Age: Avicenna and Early Rose Distillation
The most consequential technical development in the history of aromatherapy is the refinement of steam distillation, and it is most closely associated with Ibn Sina — known in the West as Avicenna — the Persian physician and polymath who lived from 980 to 1037 CE. Avicenna's Canon of Medicine became a foundational text for both Islamic and European medicine, and his improvements to distillation apparatus allowed for the separation of aromatic compounds from plant material with a purity and concentration that earlier methods could not achieve.
Rose water and rose oil produced by distillation became prized commodities in the Islamic world, valued for perfumery, medicine, and cooking. The Persian city of Shiraz became so famous for its Rose production that the region's roses were known throughout the medieval world. Whether Avicenna invented distillation or refined an earlier technique is a matter of ongoing historical debate, but his documented improvements and the scale of production that followed in the Islamic world represent a genuine technological threshold in the history of aromatic extracts.
Medieval Europe: Plague Doctors and Monastic Distilleries
Medieval European engagement with aromatic plants ran along two tracks that only occasionally converged. The first was monastic medicine. Benedictine and other religious orders maintained herb gardens and distilleries and produced medicinal preparations — including aromatic waters — for use in their communities and for distribution to the poor. The monastery at Saint Gall in present-day Switzerland, for example, had a dedicated medicinal garden whose layout is preserved in a famous ninth-century plan.
The second track was popular response to epidemic disease. The bubonic plague, which devastated Europe repeatedly from the mid-fourteenth century onward, generated enormous anxiety about infection and contaminated air. The miasma theory of disease — the belief that bad air caused illness — made aromatic fumigation seem like rational prophylaxis. The iconic plague doctor costume, with its beak-shaped mask stuffed with aromatic herbs, is an image from seventeenth-century Italy, but the underlying logic had been present in European and Chinese medicine for centuries. Whether the herbs and resins used actually offered any protection is a separate question from the fact that they were used systematically and deliberately.
European distillation technology advanced through the medieval and early modern periods, partly through contact with Islamic scholarship and partly through independent development. By the sixteenth century, aromatic waters and what contemporaries called "chemical oils" were being produced across Europe for medical, culinary, and cosmetic purposes.
The 19th Century: Perfumery, Chemistry, and the Isolation of Constituents
The nineteenth century transformed the understanding of aromatic plants by introducing the tools of organic chemistry. Scientists began isolating and identifying the specific chemical compounds responsible for the characteristic smells of various plants — linalool from lavender, eugenol from cloves, menthol from peppermint. This process of constituent isolation had two important consequences.
First, it made synthetic reproduction possible. By the end of the nineteenth century, chemists were producing artificial versions of aromatic compounds in the laboratory, which laid the groundwork for the modern fragrance and flavor industry. Second, it created a conceptual split between the "natural" aromatic plant and the "chemical" isolate — a distinction that would become culturally charged in the twentieth century.
The perfumery industry, centered in Grasse in southern France, was a crucial commercial context for essential oil production during this period. Families in Grasse had cultivated aromatic plants, particularly Rose and jasmine, and extracted their essences for perfumers in Paris for generations. This industry supplied both the raw materials and the technical knowledge that a young French chemist named René-Maurice Gattefossé would later draw on.
René-Maurice Gattefossé and the Coining of "Aromathérapie" (1937)
René-Maurice Gattefossé was a chemist who worked in his family's perfumery business in Grasse and became interested in the potential medicinal applications of essential oils. The story most often told about him involves a laboratory accident — an explosion that burned his hand, after which he plunged the hand into Lavender essential oil that was nearby. He reportedly observed that the wound healed with unusual speed and without infection, and this experience deepened his interest in essential oils as therapeutic agents.
The details of this account come largely from Gattefossé's own writings, and some have been embellished in popular retellings. What is documented is that Gattefossé spent the subsequent years researching essential oils systematically and in 1937 published a book titled Aromathérapie: Les Huiles Essentielles, Hormones Végétales. This book coined the term "aromathérapie" and argued that essential oils had specific physiological effects beyond their fragrance — a claim that distinguished them from mere perfumery ingredients and positioned them as subjects for scientific investigation.
Gattefossé's work was not widely adopted by mainstream medicine, but it established a vocabulary and a framework that later practitioners would build on.
Jean Valnet, Marguerite Maury, and the Post-WWII Clinical Wave
Two figures in the decades following Gattefossé were particularly influential in shaping what aromatherapy became in the late twentieth century. Jean Valnet was a French physician who had used essential oils on battlefield wounds during the Indochina War and later wrote Aromathérapie, published in 1964, which presented a clinical approach to essential oil use within a medical framework. Valnet advocated for the internal use of essential oils under medical supervision — a position that remains standard in French clinical aromatherapy but is generally discouraged in Anglo-American practice.
Marguerite Maury was an Austrian-born biochemist and beautician who brought aromatherapy into the sphere of holistic health and massage therapy. Where Valnet focused on clinical and internal applications, Maury developed protocols for diluting essential oils in carrier oils and applying them through massage — a methodology that became the dominant approach in British and American aromatherapy. Maury's student Robert Tisserand later became one of the most important English-language writers on essential oil safety, and his work on safe dilution practices and contraindications has been foundational for professional training programs.
The International Federation of Aromatherapists was founded in the United Kingdom in 1985, marking the institutionalization of aromatherapy as a distinct professional discipline.
Contemporary Aromatherapy: MLM Marketing, Safety Standards, and Clinical Research
The late twentieth and early twenty-first centuries produced two simultaneous and somewhat contradictory developments in aromatherapy. On one hand, genuine scientific research into the pharmacological properties of aromatic plant compounds expanded substantially. Studies on Lavender and anxiety, on the antimicrobial properties of tea tree oil, and on the neurological effects of various inhaled compounds appeared in peer-reviewed journals with increasing frequency. Research institutions in Europe, Japan, and North America began treating essential oil constituents as legitimate subjects of rigorous investigation.
On the other hand, the essential oil market in the United States was transformed by the rise of multi-level marketing companies, most notably doTERRA and Young Living, both founded in the mid-2000s. These companies built large distribution networks and cultivated intense brand loyalty among consumers, but they also generated substantial controversy for distributing marketing materials that made therapeutic or medical claims about their products — claims that in some cases resulted in warning letters from the U.S. Food and Drug Administration.
This commercial landscape has complicated public understanding of what aromatherapy is and what it can reasonably be expected to do. Safety standards developed by organizations such as the National Association for Holistic Aromatherapy and the International Organization for Standardization provide guidelines for dilution, contraindications, and quality testing, but these standards exist at some distance from the marketing practices of the largest commercial players.
The honest picture of contemporary aromatherapy is one of genuine scientific interest in aromatic plant compounds, a professional practice community with increasingly rigorous training standards, and a consumer marketplace flooded with therapeutic claims that outrun the available evidence. The history reviewed above does not resolve that tension — but it suggests that aromatic plants have been both overpromised and underestimated in more or less every era they have been used.

Who invented aromatherapy? No single person invented aromatherapy. The use of aromatic plants in medicine, ritual, and daily life predates written history and developed independently across Egypt, India, China, and the ancient Mediterranean world. The word "aromatherapy" was coined by French chemist René-Maurice Gattefossé, who published a book using the term in 1937, but the practices the word describes are thousands of years older.
Is the Gattefossé lavender burn story true? Gattefossé described burning his hand in a laboratory accident and applying lavender essential oil in his own writings, and the account is generally accepted as having a factual basis. However, many popular retellings have added dramatic details and specific outcomes that are not documented in Gattefossé's original texts. The story should be understood as a plausible personal account that influenced his subsequent research interests, not as a controlled clinical demonstration.
What is the earliest known record of distillation? The historical record on this is genuinely contested. Terracotta vessels from the Indus Valley civilization dated to around 3000 BCE have been interpreted by some researchers as distillation apparatus, but this interpretation is not universally accepted. Clearer documentation of distillation as a systematic technique comes from the Islamic world, particularly from the work of scholars such as al-Kindi in the ninth century CE and Avicenna in the late tenth and early eleventh centuries.
What is the oldest known essential oil? Determining the "oldest" essential oil depends on how you define the term. If you mean aromatic plant materials used for their volatile compounds, Egypt and Mesopotamia both have records going back to at least 2000 BCE. If you mean something closer to the concentrated distilled essential oils used today, the earliest well-documented examples come from the Islamic world in roughly the tenth century CE. Frankincense and Myrrh resins are among the most consistently documented aromatic materials across ancient cultures.
When did aromatherapy arrive in America? Aromatherapy began reaching American consumers in a meaningful way during the 1980s, partly through the translation and popularization of British and French aromatherapy texts and partly through the growth of the natural health and New Age markets. The founding of the National Association for Holistic Aromatherapy in 1990 marked an early effort to establish professional standards in the United States. The mass-market expansion came with the rise of MLM essential oil companies in the 2000s and 2010s, which brought essential oils into mainstream American consumer culture on a scale that earlier practitioners could not have anticipated.
