A fantastic and mysterious relationship is continuously unfolding between plants and their surroundings. These organic green machines are ceaselessly performing a glorious alchemy with water, soil, air and sunlight. The nearly infinite possible combinations of plant genetics and environmental conditions on the face of the earth have allowed for an almost immeasurable diversity of alchemic floral expression, resulting in a vast array of natural botanical materials. These range from simple staple foodstuffs to gourmet fruits and vegetables, from rich exotic spices to effective medicinal herbs, and from enchanting natural perfumes to complex therapeutic essential oils. Mankind is reaching ever further into the jungles and rain forests, knowing that nature is the true master of creation in these fields.

The distinction in plants between food and medicine is blurred at best. Researchers regularly report new medicinal properties in plants once considered salad fixings, or even just weeds. Fruits and berries once thought supremely plain nourish us with some of the world's most potent anti cancer agents. The same goes for common teas and spices; green tea is arguably the most effective anti oxidants known. The Indian spice Turmeric has fantastic anti-inflammatory properties...and this list continues to grow. This lack of distinction also exists between natural fragrances and therapeutic essential oils. The oil of Lavender flowers, rich in ketones, does triple duty as a perfume, an effective anti-inflammatory and anti-microbial agent, and calming aromatic that can help ease tension and allow restful sleep.

The use of so-called 'alternative' therapies is on the rise; more individuals are turning to the wisdom of nature for assistance for all types of ailments, both physical and psychological. Interestingly, the source of most ills, from a naturopathic point of view, is being out-of-balance with nature. Eating unnatural things, following unnatural cycles, and living in unnatural environments. Lack of balance with the earth, from which we are made and upon which we live, leads to 'dis-ease' in our bodies and minds. As plants have created their wondrous botanical materials in a process guided by the rhythms of the heavens and earth, we may look to 'plant wisdom' to lead our way back into balance.

A depressed mental state is a common reasons for seeking treatment through alternative therapies. A wide range of psychological and physical issues can result in feelings of depression and an outlook of negativity. Further, once in this state, patterns can persist that make relief much more difficult to come by. Many natural healers believe depression to be a result of, like many other ills, of being out of balance; being unable to 'sync up' with the natural state of harmony that permeates the universe. Using the concentrated aromatic oils of plants for uplifting one's mental state is truly mainstream in some parts of the world due to essential oils' significant positive effects. Aromatherapy itself may or may not directly affect the underlying cause of depression, but it may provide just enough support so that the depressive cycles can be broken.

In humans, the olfactory (sense of smell) region is an area of about 2 and a half square centimeters, and is located in each of the two nasal cavities between and below the eyes. Containing approximately fifty million primary sensory receptor cells, this region is highly intricate, being 10,000 times more perceptive than the sense of taste. When compared to sight, we find that olfaction is more complex - it is able to distinguish a nearly infinite number of element compounds at very low concentrations. In order to perceive the visible spectrum, humans use only three types of photoreceptors; in contrast, the sense of smell relies on several hundred distinct classes of receptors.

Essential oils stimulate multiple regions in the human brain, including those controlling our hormonal and emotional reactions. Aromatic oils have direct and profound effects on our innermost control systems which balance our feelings and mental states. When inhaled, aromatherapy oils passing through the outer layers of the sinuses and activate the olfactory nerves. There, the brain is directly stimulated, producing powerful systemic effects, with the most immediate being on the emotions.

In both Naturopathy and Ayurvedic Medicine (The Science of Life), essential oils are considered to enhance the flow of prana (essential life force), enhance and nourish ojas (sustaining energy and immunological essence), and brighten tejas (clarity and mental luminosity). In Traditional Chinese Medicine, essential oils in general are medicines for the Shen, the spiritual essence that resides in the heart and guides and governs consciousness. Used consciously, essential oils powerfully enhance positive mental and emotional states.

Further, the medicinal properties of essential oils, through their ability to support physiological (physical body) healing, can also be of great benefit to the heart and mind. A Korean study on the effect of aromatherapy on pain in patients with arthritis found that receiving massage with lavender, marjoram, eucalyptus, rosemary, and peppermint oils significantly decreased both the pain AND mental depression levels.

Following are some oils that have a reputation for up-lifting Shen, enhancing prana, nourishing ojas, and brightening tejas - combinations that may have marked effects on symptoms of depression. These oils can be used alone or in combination in a nebulizing diffuser (producing a fine mist of oils for inhalation), or in aromatherapy massage, thereby inhaled and absorbed through the skin concurrently.

Bergamot oil, cold pressed from the rinds of bitter oranges, has a great reputation uplifting the mind and spirit, while bringing calm. For this reason, is suitable for many types of depressive states, particularly those with a strong current of negativity.

Neroli (from the flower of bitter oranges), like Bergamot, regulates the Qi - and like Jasmine flower oil, comforts the mind and heart. Neroli is called for at a core level, for the type of depression that comes from nervous and emotional exhaustion. Neroli uplifts the mind and Spirit with its potential to nourish and unify. Neroli assists in retrieving and releasing repressed emotions, with potential to nourish and unify a fragmented psyche. Neroli is specifically indicated for individuals who, in order to escape from emotional pain and suffering, cut themselves off from their feelings and senses.

The essential oil of Chamomile flowers is used when the depression manifests in a moody, irritable, dissatisfied outward expression. Chamomile essential oil is earthy, rich, and grounding with significant calming and uplifting qualities.

When depression is of a Fire (overly aggressive) nature, it often involves an imbalance of joy and love - the root emotions of the heart and mind. Joy is an extension of Shen's (spiritual essence's) innate sense of harmony and perfection, an experience of emotional and spiritual well-being. The depression that afflicts the heart and Shen involves a loss of one's natural sense of joy. There is often an accompanied lack of enthusiasm and interest as well as an inability to become inspired. Rose otto - steam distilled rose essential oil - or Rose Absolute may have a profound effect on this state. Rose is thought the premier heart opening aromatic, bringing joy, uplifting and restoring balance.

While aromatherapy can provide support in many cases, it may not be for everyone. Seek professional assistance in any case where one is losing the will to live, or any other seemingly impossible situation. Aromatherapy can be used in concurrently with other treatments, though one should consult their care giver to ensure there are no contraindications with any prescribed medication.
