Aromatherapy — a fragrance art whose origins trace back to Ayurveda, later spreading through the Western world and developing over a long history.
The fields connected to aromatherapy and herbs are diverse. Some people simply wish to incorporate natural scents into daily life, while others work in sales, manufacturing processes, spatial fragrance design, medical or caregiving settings where essential oils are used, or as instructors.
Aromatherapy essential oils and herbs are used as raw materials for cosmetics, bath products, and ambient fragrance design. Today, they are closely integrated into everyday life and widely utilized both professionally and as daily consumer goods.
In professional environments, qualifications may be required—or not—depending on the industry. Knowledge does not necessarily correlate with certification. Because aromatherapy and herbal practices influence both body and mind, the scope of learning is broad. In some cases, individuals without formal qualifications may possess deeper knowledge than certified practitioners. As in any profession, continuous learning is essential, and the world of aromatherapy and herbal work evolves day by day.
This site is operated to support information gathering, study, and decision‑making for anyone interested in aromatherapy and herbal practices. From beginners to experienced professionals, we hope this resource helps you organize knowledge and deepen your understanding of fragrance and spatial design.
※ Aromatherapy and herbal use are based on self‑responsibility.
※ Essential oils (aromatherapy essential oils) are lipophilic. Products labeled “aroma oil” or “water‑soluble” are not true essential oils, so please take care when using them.
※ The essential oils listed below are examples; you do not need to use all of them.
※ For blending, it is recommended to start with one main essential oil and use a total of about three types, which is easier to manage.
※ Always check physical condition, mood, contraindications, and medical history, and use within an appropriate dilution range.
※ Aroma crafts should be made in amounts that can be used once, or stored in a cool, dark place and used within 3–7 days. ※ For treatment oils, a patch test is recommended.
※ After aromatherapy inhalation, ventilate the room. If you feel unwell, stop use. If skin trouble occurs, rinse with plenty of water. ※ For contraindications, please refer to the relevant page on this site.
