Scents bypass the thalamus and head straight to the olfactory bulb, which is directly connected to the hippocampus (which is responsible for your memory) and the amygdala (where you process your emotions). Because odors are first routed through these regions before reaching the thalamus, they’re more closely linked to memory. This study finds that certain scents that evoke positive autobiographical memories may be able to also lift the mood and reduce stress. Certain scents will certainly help you boost your feelings.Cinnamon: Increases motor response + improves performance on task that requires attention.Ginger: Fights Fatigue Eases PainPeppermint: Sustains Attention plus Enhances memory accuracyPine: Elevates mood, increases alertnessLavender: Recharges the Brain improves concentration.Citrus: Increases alertness shortens response time.Jasmine: Re- energizes the body lifts the mood.Lemon; Arouses the senses and decreases errors.Coffee: Enhances analytical reasoning, promotes attentiveness.Vetiver: Improves brain function, boost concentration.Rosemary: Increases alertness, improves memory.How are fragrances Made.Since very long time, humans have been using scents from nature to produce pleasant for both men and women. Humans use all sorts of scented items daily, lotions, candles, cleaning products, personal fragrances to name some. Well explain the process used throughout history, you might be surprised how much work goes into making your favorite fragrance.Perfume in Ancient TimesIn archaic time periods, perfume makers did not have the ability to manufacture synthetic smells. All fragrances came from the earth in one way or another. Ancient civilizations infused body lotions and water with aromatic flowers and different types of wood. They also burned incense made of spices, like cinnamon and myrrh, and extracted oil from plants.Before the manufacturing process can begin, the plant and animal-based perfume ingredients must first be gathered (ingredients listed below). Various methods of extracting plant oils have been used throughout the world over time. When early civilizations extracted oils, they typically used the expression method, which we’ll dive more into later on.Throughout the ages, perfume extraction and manufacturing methods were developed and innovated. Not only did perfume serve as a ceremonial and symbolic cosmetic, but it opened up a new avenue for trade.The Perfume Manufacturing ProcessMaking a perfume involves collecting ingredients, extracting oils, blending, aging and quality control. Almost like a fine wine, a lot of work and time go into producing a perfume. What’s especially interesting is that many of the methods from ancient times are used by popular perfume brands today.Of course, the techniques and mixtures have been finetuned and perfected by scientists and other professionals, but some procedures are very similar to their early counterparts, such as expression. Keep reading for all you need to know about the perfume manufacturing processExtraction MethodsNatural ingredients must have their oils extracted in order to create a perfume or cologne. Essential oil extraction can be done several ways: Oils can be obtained through solvent extraction, steam distillation, expression, enfleurage (a process that squeezes out the oils) or maceration.Check out some of the various tried-and-true extraction methods below, both ancient and modern. Some methods you may be able to DIY at home, but others you might want to leave to the professionals.Blending the IngredientsThe process of creating a scent begins after the essential oils are extracted and collected. Once all the ingredients have been chosen, they need to be blended together. The oils are blended according to a formula that has been predetermined by a master in the perfume industry, often referred to as a “nose.” Many of these formulas were carefully created over several years and often include hundreds of different ingredients.As we mentioned before, some perfume ingredients come from plants and some are animal products. For example, castor comes from beavers, musk from male deer and ambergris from the sperm whale. Animal substances are often used as fixatives that enable perfume to evaporate slowly and emit odors longer.Other fixatives include coal tar, mosses, resins or synthetic chemicals. Alcohol and sometimes water are used to dilute ingredients in perfumes. It is the ratio of alcohol to scent that determines the perfume’s strength and worth. The more essential oil, the stronger (and more expensive) the perfume is.Eau de parfum will have a lower concentration of alcohol while body mists will have a much higher concentration of alcohol.The Future of the Perfume Industry Today, perfumes are increasingly made using synthetic chemicals. Often, scents that occur naturally are reproduced synthetically rather than sourced and extracted. This allows the cost of producing perfume to go down, increasing its availability to the public.Our sense of smell is the most powerful of the five senses, so it doesn’t look like perfumery is going away any time soon. The importance of scent has been around since the beginning of time, meaning smell is valuable for a multitude of purposes, including emotion, memory, creativity and relationships.Because of the significant impact of our olfactory sense on our daily lives, research is being conducted in the areas of synthetic human perfume (recreating human body scents i.e. pheromones) and aromatherapy. Perfume can go so far as to boost human emotional states and physical arousal.
