Yeh Family History

Natural Perfume Industry was originated by the Yeh family in China during the 1930’s. Three brothers, Xin Nong Yeh, Ru Yu Yeh & Zhong Tao Yeh who were herbal pharmacologists, perfumists, engineers and chemists began their research about natural perfume in Shanghai, China. Each were talented and gifted in perfumery & manufacturing and thus were honored as “Fathers of Cosmetic & Perfume Industry”.The Yeh family founded the Royal Perfume & Cosmetic Industry and raised the natural perfume industry to a very high scientific level. This set the foundation for the perfume industry in all of China. As a result of their research, Chinese production of oriental perfumes and essential oils are widely accepted by the entire world.

We are the third and fourth generation of successors and we are continuing the Yeh family tradition here in the United States, using the secret formulations, manufacturing techniques and engineering methods that took over 120 years to master and are only handed down from generation to generation.


Yeh Perfumatherapy

Natural perfume therapy is an important part of medicine and presents many health benefits. The significance lies within the healing properties of each natural aroma and how it affects the body both mentally and physically. Perfumatherapy encompasses the interdisciplinary science of natural medicine, natural perfume, and perfumery. It is important to learn this essential part of natural medicine to help others benefit from the health and healing that natural fragrances offer.

We are the third and fourth generation successors to the Royal Yeh Natural Perfume and Cosmetic Industry. Utilizing the perfected formulas that have been handed down by family, we have developed a line of natural perfumes that are not only wonderful to smell, but contain therapeutic properties as well. Our perfume line contains essential oils that are extracted straight from nature. These aroma-essentials are light, refreshing, fragrant, and beautiful.

Drs. Timothy and Pearl Yeh’s perfumes contain essential oils – the highly concentrated extracts from plants, herbs, and flowers. 

  • Essential oils act on the olfactory nerves which lead from the nose directly to the brain
  • Essential oils contain anti-bacterial, anti-viral, anti-microbial, anti-infectious, anti-septic, anti-tumor, anti-fungal and immune stimulating benefits and other therapeutic properties
  • Essential oils are organic and act in harmony with the body, providing well-being and balance

Natural plants are the basis for both the perfume and cosmetic industry and natural herbal medicine. However, here in the United States, perfume is mainly used for its pleasant smell and ignored for its other possibilities. By introducing natural medicinal herbs into perfumes, a perfume is obtained that would have the qualities of being fragrant, aromatic, therapeutic, medicinal and natural.

The origin of using natural herbs in medicine and perfume began in China, Egypt and India. After the tenth century, the art of making perfume spread to Bulgaria and France. The 12th and 13th centuries marked a period of time when Europe became immensely attracted to Asian perfume. Exotic scents and spices from the Far East were highly demanded. Clove, cinnamon, pepper and nutmeg were just some of the things that were imported from Asia. Since then, these have become the four main scents to enter the daily life of Europeans.


Ingredient Extraction

For over a thousand years, scientists have researched the area of perfume and natural herbal medicine. However, in recent history, perfume specialists and herbal pharmacists have used different methods to come to the same conclusion about the planting, harvesting, preserving, processing, ingredient analysis, ingredient extraction, and functional study of natural plants.
Ingredient extraction and functional study of natural plants have especially become the center of focus in recent years. Different techniques have been developed. For example, the Germans have extracted plant ingredients at temperatures below 273 Kelvin. Liquid carbon dioxide was used by the Chinese to extract plant ingredients.

The extraction processes of nutritional foods, perfumes and herbal medicine are the same. The conclusion was that there are pharmacological effects as a result of different combinations of ingredients extracted; volatile oil is an example. The function of volatile oil can be used as a medicinal healing herb. Research from different perspectives show that the treatment effect is from the perfume scents.

The best example is from the well-known phenomenon of Chinese moxibustion. Moxibustion gives off a volatile scent that penetrates the epidermis of the skin and stimulates the nerve and regulates the vital organs and organ systems. This can accomplish an analgesia goal.


Therapeutic Effects of Perfumes

In reality, perfumes that regulate the nervous system have been known for a long time. Smelling fragrant flowers can soothe the mind, increase memory and enhance work performance. Recently, the Rakujima Company located in Tokyo, Japan (This company occupies the second largest building in Japan) used a perfume containing woody note, flower fragrance, and orange peel to help their employees. They used this perfume in their company at different hours to regulate the employee’s concentration energy to work and preparation to work.Today, the natural perfume industry includes over 70 families and 500 different species of plants. At the 54th annual International Perfume Convention, specialists from all over the world discussed medical applications of perfume on physiology and psychology. The psychological and physiological effects of medicinal perfume interested the Shiseido company and so they performed tests on their employees. They came to the conclusion that perfumes decreased the pressure of the offices and are wonderful to relieve stress.

The introduction of natural medicine into the perfume and cosmetic industry is a revolution for modern day. For example, a new breakthrough fragrance can combat the common cold. Medicinal herbs are now widely used in perfume as the essential ingredients. Patchouli, Gardenia, Clarysage Oil, Angelica Sinesis Oil, Silver Divaricata Oil are a few of the essential ingredients used in medicine perfume. They are now used in the mainstream of Asia. We are proud of the accomplishment and our wish is that everyone will use and develop this new revolutionary perfume industry based on natural medicine.

Perfumatherapy is a natural method to care for mind, body and soul using pure essential oils. Aromatherapy means to treat with aroma through inhalation. Essential oils, because of their fragrance and volatility, have been reported to help create greater spiritual, physical and emotional harmony when inhaled. A Few Examples:

  • LAVENDER is most recognized for burns, headaches, cuts, bruises, skin irritation, insomnia, itching, PMS, stress and hair loss. The fragrance is calming, relaxing, and balancing, both physically and emotionally.
  • LEMON has been found to promote leukocyte formation, to dissolve cellulite, to increase lymphatic function and promote a sense of well-being. It is beneficial for the skin, serves in the purification of air and water and dissolves gum and grease spots.
  • PEPPERMINT has been found to improve mental accuracy, soothe the respiratory system and may relieve nausea, fever, vomiting and acid stomach. It may also be used for air and water purification. Recently clinically tested, peppermint improves mental acuity by 28%.


Essential Oils

Essential Oils are the subtle, aromatic and volatile liquids extracted from the flowers, seeds, leaves, stems, bark and roots of herbs, bushes, shrubs and trees through distillation. According to ancient Egyptian hieroglyphics and Chinese manuscripts, priests and physicians used essential oils to heal the sick. They are the oldest form of medicine and cosmetics known to man and were considered more valuable than gold.There are 188 references to oils in the Bible. The wise men brought the Christ Child gold, frankincense and myrrh. Clinical research now shows that frankincense oil contains very high immune stimulating properties. In Exodus, God gives Moses the formula for “a holy anointing oil”. (Exodus 30:22-25).

Some of the precious oils which have been used since antiquity for anointing and healing the sick are frankincense, myrrh, galbanum, hyssop, cassia, cinnamon, and spikehard. Science is now beginning to investigate the incredible healing substances found in essential oils. Yeh Essential Oils are 100% PURE and ORGANIC and they have the following benefits:
Immune Stimulating

Essential oils are the basic materials for Aromatherapy. As plant extracts, they should represent or contain the nature, essence and biochemistry of the plants from which they were obtained. Therefore, the starting material should therefore be of the best and highest quality. The plant itself, growing methods, soil, position, country of origin, seasonal conditions, and harvest method, will all play an important part in the final determination of quality.

By definition an essential oil is obtained by steam distillation. An essence is obtained by pressing or scarification. Some methods are more sympathetic than others. Distillations can alter the quality of the original plant material. Consideration has to be given to the distillation still, its type, steam heat and pressure controls, length of distillation time, and the purpose of the end product.


Scientific Prospectives of Natural Perfumes

It is common knowledge that the nose can detect different scents. In 1991, two scientists from Columbia University discovered that a human nose is able to differentiate over 10,000 scents. This job depends on many smell receptors, which senses the impact of the air-born scent molecules. Each smell receptor is reserved for its own smell molecule and not for any other.Recently, several scientists at Yale University concluded through a 5-year study that natural essential oil molecules travel from the olfactory nerve ending fibers through the hypothalamus and pituitary gland to the lymbic center. At this time the released substances from the essential oil, stimulates the emotion control center affecting the autonomous nervous system in the brain trunk to have a great adjustment of physiologic and psychological activities.

The research also pointed out that the olfactory nerve could not differentiate the synthetic perfume from the natural. However, when the synthetic perfume went to the brain, the brain did not produce a-wave at all, as did the natural essential oils. The a-wave is a good wave to make one feel happy and healthy. This clearly demonstrates that natural essential oils and perfumes are treasures to our health. Natural perfume does not only create an affect through the nose, it can also be absorbed by the skin to affect different organ systems. The body is normalized according to the nature of each individual essential oil. Therefore, to have the qualification and mastery of perfumes, one should have good training and study for at least 3-5 years.

Natural & Synthetic Perfumes

rom early times to the end of the seventeenth century, humans relied fully on natural medicine and natural perfume for healthcare and treatment. This was called the peak period of natural medicine. From the beginning of the eighteenth century through the end of the twentieth century, the chemical medicine industry and the superiority of Western economies developed rapidly. Therefore, the synthetic chemical drug and perfume companies rose and filled in the market both domestically and internationally.In just a few hundred years, the magnificence of nature was replaced with synthetic chemical compounds that were simpler to control. Thus drugs and synthetic perfumes won the appreciation and acceptance by the majority of the public, replacing the great beauty, deep imperishable knowledge and quality of nature. Many of these synthetic chemicals have caused people to suffer from adverse and lethal side effects.

General Introduction

The natural perfume and pharmaceutical industry established about the same time and originated from natural wild plants. They were classified together because their functions were interdependent. For example, people first took the wild rose as food, because of its pleasant smell, taste and beauty. Later, it was found that roses could be used to heal sore throats and was utilized to guard against plagues and pestilence. Cinnamon bark, mint, and patchuli also developed in the same manner. These were the beginnings of natural
perfume therapy.

Five thousand years ago, medicine and fragrance were not yet separated. During this time, there lived a man named Shennon. He smelled and tasted hundreds of herbs and wrote down their medicinal values and compiled a detailed text. Also during this time, the writings about the effects of fragrant medicines and ointments as well as the formulas for different perfumes were written down in medical books found in Mesopotamia. It has been noted that people in ancient times also used perfumes in times of celebration and for ceremonies.Egypt, China, and India were the first three countries to make and use perfume products. Between the twelfth and thirteenth century, these oriental perfumes and fragrances became very popular and began to play an important part in the daily lives of people in Europe. When Marco Polo of Italy explored China, he learned the techniques of how to manufacture and use Oriental perfume. Afterwards, the technique was spread into Bergalia and France, and hence the knowledge of making perfume was then quickly developed. During the fifteenth century, two Portugese scholars, Magirun and Giarma, came to China to research Oriental perfumes.

Aromatherapy & Perfumatherapy

In 1937 Dr. Gattefosse, a French cosmetic chemist, published a book first named AROMATHERAPY. He wrote this book after he had survived a lab explosion in July of 1910. He used lavender to treat his wound, and it healed without a scar. Robert B. Tisserand, editor of the International Journal of Aromatherapy, researched aromatherapy for 20 years. After his research, he wrote a book “The Art of Aromatherapy” in 1983. Dr. Gary Young also specializes in aromatherapy and wrote a book, “Desk Reference” published in 2000, about essential oils.
Aromatherapy is widely used and accepted all over the world.
It is great because:
1) Essential oils are very powerful for healing.
2) The results of using essential oils are phenomenal.
3) The missing medical components of herbs are found and recovered.
4) It is able to amend the lost medical effects of herbal medicine.
5) The use of essential oils is looked as the extension use of the missing part of herbal medicine.
But we have to know that aromatherapy is,
1) Not related to the field of natural perfume
2) Not being managed with any step of perfumery
3) Not perfumatherapy. The smell of many blends are very unpleasant, strong, harsh or even unacceptable.
4) Not related to science and the art of perfumery

Natural perfume medicine is the cutting edge science of natural medicine, natural perfume science, and the science of perfumery. Natural perfumatherapy is a subdivision of natural perfume medicine and has been a part of the Yeh family history for over 120 years. Perfumatherapy encompasses the interdisciplinary science of natural medicine, natural perfume, and perfumery.The development of perfumatherapy is based upon the level of fragrance note.
The development of perfumatherapy is based upon medical results.

Natural perfume therapy is an important part of medicine and presents many health benefits. The significance lies within the healing properties of each natural aroma and how it affects the body both mentally and physically. It is important to learn this essential part of natural medicine to help others benefit from the health and healing that natural fragrances offer.

600 Trillion Cells in our Body!!!
There are 600 trillion cells in our body and every minute they depend upon oxygen, vital nutrients, protein and water to maintain their normal function. The ideal bioelectrical frequency for our body is an average of 70HZ. If this number drops to 58HZ, the human body catches the cold and at 57HZ, the flu. At 55HZ, the human body contracts candida and at 52HZ, EBV infections. If this frequency drops down to 42 HZ, the result is cancer.
Because the surrounding environment dramatically changes, our cells are constantly under attack by chemicals, drugs, pollutants, micro-organisms, electrical waves, radiation, and genetically modified foods. These create and cause emotional and physical stress on our body. When the body is constantly bombarded with these harmful negative factors, the bioelectrical frequency begins to drop, and it is more difficult for the body to utilize natural essential nutrients to counterattack the damage.
Therefore, it is very important to strengthen the body’s defense mechanisms and boost the immune system. At the same time, we need to find ways to lessen the environmental attack and physical and emotional stresses on our body. Medicinal herbs, nutritional supplements and good dietary guidelines are essential and should be utilized daily to combat the negative exo- and endo- factors.
In addition, the essence of various flowers, leaves, fruits and roots will benefit and oxygenate the body. It is found that the ingredients in Pearl No. 1 contain bioelectrical frequencies of 118HZ to 320HZ. This unique formula helps defend the body against infections caused by virus, bacteria and fungus, thus benefiting sinusitis, sinus headaches, allergies, asthma and respiratory infections. Pearl No. 1 benefits the mind by sending oxygen and vital nutrients to the brain, which helps alleviate depression, memory loss, unclear thinking, tension, and stress.
