Abstract
Plants are an important source of many products and play a significant role in the human lifestyle all over the world. Plants produce secondary metabolites in which essential oil is one of the important chemical constituents. It has a unique aromatic smell and is used in different industries for various biological activities. In Ayurveda, essential oil is used in aromatherapy which is an ancient therapeutic knowledge or practice for healing the health of humankind. Thus, this paper focuses on all important aspects such as essential oils and their applications, taxonomic details of essential oil-bearing plant species, IUCN status, chemical composition, and therapeutic significance.

Introduction
Plants are an important source of many
products and play a significant role in the human lifestyle all over the world. They produce two
types of metabolites, i.e., primary and secondary metabolites. Primary
metabolites include amino acids, nucleic acids, organic acids, carbohydrates, vitamins, lipids, and hormones which are quite
significant for plant metabolism and their existence. Whereas secondary metabolites are
organic compounds including
terpenes, phenols, alkaloids, sulfur-containing compounds, and essential oils [1-3].
Essential oil is a
secondary metabolite substance made up of volatile compounds responsible for its
special flavor and odour. The aromatic oil compounds are found in cells, secretory
cavities, or glandular hairs of various parts of the plant-like root, stem, bark, leaves, bud,
flowers, fruit, and seeds. The unique aroma makes the plant different
from others which is why some plants can be identified easily by their
fragrance such as basil, rose, jasmine, lavender, sandal, mint, peppermint, rosemary,
citrus, camphor, cardamom, clove and many other plants. The organic compound
of essential oils possesses anti-microbial, anti-viral, anti-oxidant, antiseptic, anti-hypertensive, anti-inflammatory, anti-biotic,
antidepressant, antiseptic, antispasmodic properties and also has good
psychogenic effects such as relieving stress and treating depression and insomnia [1, 2, 4].
Historical evidences reveal that aromatic oil has been used for various purposes such as medicinal, magical and religious ceremonies around the world for centuries. It is believed that essential oils and scented ointments were used between 3000 and 2000 BC, in Indian and Chinese traditional medicinal systems which refer to many essential oil-producing aromatic plants and their healing effects. During the same period, ancient Egypt used essential oil & ointment for physical and physiological benefits, cosmetics, culinary and spiritual purposes. Greek history also documented the use of thyme, saffron, marjoram, peppermint and cumin in their healing systems. In the 18th and 19th centuries, the active component of essential oils was largely documented by many researchers and chemists who played an important role in creating awareness about the aromatic natural compound, their quality, and their effect on human health [5, 6, 23].

2.1 Essential oils
Essential oils
refer to natural, aromatic, volatile plant oils which are secondary metabolite
products of plants that include terpenes, phenolic compounds, alkaloids and
sulfur-containing
compounds. These compounds
are responsible for the unique odour, flavor and biological activities of the
plant parts such as roots (Angelica), stem (Mentha, geranium), bark (Sassafras), wood (Sandalwood, rosewood), leaves (Basil, menthe, oregano), flower (Jasmine, rose, lily), fruit (Vanilla), peel (Bergamot), seed (Basil, coffee beans, nigella, almond) and berries (Juniper, pimento). These oil-containing
compounds are found in special cells, oil-sac, and oil-secretory glands
of the plant. These compounds
are found in limited plant species which can be identified by their aroma. These aromatic
plants belong to several families, but are abundant in the families like Apiaceae,
Asteraceae, Geraniaceae, Lamiaceae, Lauraceae, Leguminosae, Poaceae, Rutaceae, and
Zingiberaceae. These oils are generally
obtained by hydro or steam distillation extraction method. Due to the
presence of various amazing medicinal properties, several people prefer
essential oils to other prescribed medicines. Essential oil exhibits
antiviral, antibacterial, antifungal, antiseptic, anti-inflammatory, antidepressant, antineuralgic,
antivenomous, antirheumatic,
antispasmodic, antitoxic, sedative, nervine, digestive, analgesic,
carminative, decongestive, expectorant, deodorant, restorative, circulatory,
diuretic, vulnerary,
insecticidal properties. They also assist
in reducing inflammation,
stress, anxiety, depression, pain, nausea, and headache and help in boosting
mood, improving digestion and sleep, as well as eliminating bacteria. Therefore, it is
widely used in food flavors & preservatives, cosmetics, shampoo, hair oil,
body oils, soap, lotions, insect repellent, toothpaste, laundry detergents and
other industrial products [1-2, 4-5, 24-25]. A well-known therapy, ‘aromatherapy’, is famous for its
use for physical and psychological well-being through inhalation, which shows
the wide use and healing potential of essential oils [7-9, 21]. People of many countries depend on
these plants as the source of primary medicines and also for their pharmaceutical
and other industrial applications in the countries. There is a high
demand for these plants as their oil is used around the world for several
purposes. Consequently, high
demand on a global scale puts these plants at risk of extinction. International
Union for Conservation of Nature (IUCN) considered these
plants as threatened species which listed in ‘Red data book’ under various
categories such as least concern (LC), data deficient (DD), vulnerable (VU), endangered (EN) and critically
endangered (CE). There are many plants
popular for their specific
aromatic oil or essential oil mentioned in Table.1 with their IUCN
status, characteristics, chemical compositions and various pharmacological
activities [9-11, 13].

2.2 Ayurvedic
herbalism
It is an ancient
science of India that heals various diseases and disorders through various
plants and their extracts, that’s why it is also known as a holistic healing
system or natural healing system of understanding the effects, benefits, and
inner workings of various herbal plants. It considers the taste, energy and
post-digestive effects of herbs, and explores their impact on the vata, pitta
and kapha doshas. This ancient science holds a long history of
the use of essential oils in the pre-vedic and vedic periods [10, 15-16]. The perfume and scented items were
renowned in this period for various religious and social practices. The utility of
jasmine, champak, lotus,
mango, hyacinth, basil, rose, lily, patchouli leaves, camphor, eucalyptus, sandalwood, and vetiver root in
various ayurvedic practices are mentioned in ancient literature. Ayurvedic texts
such as Charaka Samhita, Susruta Samhita, Ashtanga Hridaya, and Ashtanga Sangraha,
mentioned the use of essential oils containing aromatic herbs, resin, barks,
leaves, exudates, twigs, roots and seeds, for medicine, beauty aids, cosmetics,
and as a deodorant. In Indian
religion, incense (Dhupan) was used in
worship to offer God. According to Ayurveda, Dhupan is highly beneficial for
disinfecting the body or the room
because it includes aromatic essential oil which is rich in various biological
activities. Scented oils (Sugandh tailas) were used
topically to treat various skin
disorders. There are some
health-protective and
disease-eliminating practices in Ayurveda
named ‘Abhyanga’ include massage of
the body with aromatic oils for healthy, smooth skin; Udvartanam includes
massage with herbal, scented powder to regulate blood circulation and weight
loss; Sugandha Paniya includes a sprinkling of scented water on the body. Other ancient
literature mentions that the body becomes redolent by drinking scented water of
sandalwood, cardamom, usira (vetiver), and tagra (Indian valerian). ‘Varahamihira’ mentioned a scent
known as ‘Smaroddipana’ made from leaves
of Cinnamomum tamala Nees & Eberm (patra), Tagetes
erecta L. (Turuska), Valeriana
jatamansi Jones ex Roxb. (Tagara). Also, a scent
name ‘Bakula’ is made by
fumigation of Smaroddipana ingredients with Picrorhiza kurroa Royle ex Benth. (katuka) and Commiphora
mukul (Hook. ex Stocks) Engl (Guggulu). Elettaria
cardamomum (L.) Maton (Ela, cardamom), Syzygium
aromaticum (L.) Merr. & L.M.Perry (Clove), Piper cubeba
L.f. (Kakkola), Myristica
fragrans Houtt. (Jaatiphala), and Cinnamomum
camphora (L.) J.Presl (camphor) is used as a
mouth freshener. Clove oil is used
for dental emergencies; turmeric for microbial infection and skin diseases; basil for inflammation
and heart diseases and cinnamon to stimulate circulation etc. [11, 15, 16, 23].
This holistic
health care system prescribes the usage of different medicated oils for
application on the body, with or without massage for providing health benefits
and to treat specific indications. While most of the medicated
oils are for external usage, certain types of medicated oils that are processed
with milk are administered orally also.
Ayurvedic text with properties and uses
of the essential oil-
Tailaṁ svayonivattatra mukhyaṁ tīkṣṇaṁ vyavāyi ca.
Tvagdoṣakṛdacakṣuṣyaṁ sūkṣmoṣṇaṁ kaphakṛnna ca.
Kṛśānāṁ bṛṁhaṇāyālaṁ sthūlānāṁ karśanāya ca.
Bahuviṭkaṁ kṛmighnaṁ ca saṁskārāt sarvadoṣajit. (A.Hr.Sū.-5.55-56)
Vāgbhaṭa described the properties as: Oil is 'svayonivat' meaning it is similar in properties to the ingredients from which it is obtained. Mainly, oil is sharp and Vyavāyī in attribute. It causes skin diseases, is harmful for the eyes, enters in channels of the body due to minuteness, is hot in potency and does not vitiate Kapha [26, 29]. Vyavāyī means that which spreads in the body quickly or which first spreads into the body and then gets digested. That oil, etc. ingredients are called Vyavāyī.’Oil massage is capable of nourishing the lean person and makes obese person slim. It is more bulk promoting and vermicidal. With specific preparations the oil is capable of alleviating three Doṣa [26].
Here, the two qualities of oil are
explained-First is that oil makes
lean person obese and obese person slim. The reason behind it is that the channels
transporting Rasa, Rakta, etc. dhātu in body get constricted. Massage with oil, due to its scraping, minute,
easily penetrating properties enters in those channels and opens them. In this way, the
contraction of channels is removed and body gets nourished. Due to minuteness, oil on
massage enters into the channels of obese people
to remove cholesterol/ fat which makes him/her lean. Oil massage is very useful for all in pre-winter, rainy and Autumn seasons. Hence,
this fact is famous in Āyurveda- Ghṛtād
Daśaguṇam
Tailam mardne na tu bhakṣaṇe.’ means oil is ten times more beneficial than Ghṛta (Clarified
butter)
for massage but not for consumption
orally [30].
The second quality of the oil is that it pacifies all three doṣa with special preparation [30]. Oil is naturally Kaphavāta
alleviating due to hot potency and uncutous attribute. If it is especially prepared with candana,
etc. cold potency ingredients
then it pacifies Pitta also. Hence, due to special preparation, it is called Tridoṣa.
Properties
of oil derived from Nimba (Indian margosa)-
Nimbatailaṁ tu nātyuṣṇaṁ krimikuṣṭhakaphāpaham. Nimbataila.
(Rā.Ni.-15.117)
The oil derived from Neem seeds is not very hot in
potency. It is vermicidal,
treats leprosy and pacifies Kapha [27].
Properties of oil derived
from Kośāmra (Kusum tree)-
Saraṁ kośāmrajaṁ tailaṁ krimikuṣṭhavraṇāpaham.
Tiktāmlamadhuraṁ balyaṁ pathyaṁ rocanapācanam. Ābāḍela. (Rā.Ni.-15.123)
The oil derived from Kośāmra is laxative, treats worm
infestation, leprosy and wounds; is bitter, sour and sweet. It is a tonic, imparts taste and aids in
digestion [27].
Properties of oil derived from Karpūra (camphor)-
Karpūratailaṁ radadāḍharyakāri
vātāmayaghnaṁ kaṭu
pittakāri. Kāpurela.
Oil derived from Karpūra (camphor) strengthens the teeth, treats Vāta
diseases, is pungent in taste and aggravates Pitta [27].
Properties of
oil derived from seeds of Khasa (poppy seed)-
Tailaṁ tu khasabījānāṁ balyaṁ vṛṣyaṁ guru smṛtam.
Vātahṛt kaphahṛcchītaṁ svādupākarasaṁ ca tat. Khasakhasela. (Bhā.Pra.Ni.-20.21)

Āsannatibalā yuddhe daityādhipatayaḥ purā.
In ancient time, by the use of oils denom kings/ chiefs became Ajara (devoid of old age), Nirvikāra (devoid of diseases), fatigue free and most
powerful in wars [30].
Tailaṁ na sevayed dhīmān yasya kasya ca yad
bhavet.
Viṣasāmyaguṇatvācca yogayogyaṁ na varjayet. (Rā.Ni.-15.127)
According to Rājanighaṇṭu - A wise man must not use
any oil without consulting a physician on
his own because oil has properties similar to poison. Hence, according to Āyurveda
where ever a particular oil is prescribed, there only that oil should be used
and not any other oil [27].
Oil is having poisonous effect; it is
described as-
Viṣasya tailasya na kiñcidantaraṁ mṛtasya suptasya tathā na
kiñcit.
Ṛṇasya
dāsasya na kiñcidantaraṁ mūrkhasya kāṣṭhasya ca naiva kiñcit. (Rā.Ni.-15.128)
There is no difference between dead and slept one, debt and
servant, fool and wooden lodge similarly in oil and poison, means oil is like
poison. So, it should be utilized safely
as prescribed [26-28].
According to Ayurveda, a state (increase or decrease) is called ‘dosa visamata’. A disturbed state or imbalance state of three doshas (vata, pitta, kapha) is the reason for various diseases [11, 17].
