गंधचिकित्सा आणि अत्यावश्यक वनस्पती तेले (Aromatherapy & Essential Oils)
गंधचिकित्सा (Aromatherapy) म्हणजे अत्यावश्यक (Essential) तेलांचा औषधी व उपचारात्मक उपयोग. काही विशिष्ट सुगंधी वनस्पतींमध्ये आढळणाऱ्या तीव्र गंधयुक्त पदार्थाला अत्यावश्यक तेल म्हणतात. साधारणतः ज्या वनस्पतीपासून हे तेल मिळवले जाते, त्याच वनस्पतीचे नाव त्याला दिले जाते (उदा. चमेली किंवा लव्हेंडर); परंतु याला काही अपवादही आहेत, जसे की संत्र्याच्या फुलापासून काढल्या जाणाऱ्या तेलाला 'नेरोली' (Neroli) म्हणतात. हे तेल वनस्पतीमध्ये सूक्ष्म थेंबांच्या रूपात (Microdroplets) लहान पिशव्यांमध्ये (Sacs) अथवा ग्रंथींमध्ये (Glands) साठवले जाते. वनस्पतीच्या फुलांतून, पानांतून, खोडातून, मुळांतून, फळांतून अथवा संपूर्ण वनस्पतीचे ऊर्ध्वपतन (Distillation) करून हे तेल मिळवले जाते.
वनस्पती तेलांप्रमाणे (जसे ऑलिव्ह, कॉर्न, सोया) अत्यावश्यक तेले वंगणासारखी चिकट (Greasy) नसतात. ती वजनाने हलकी, बाष्पनशील (Volatile) आणि सेंद्रिय रसायनांच्या (आम्ले, एस्टर्स, अल्कोहोल, अल्डीहाईड्स, केटोन्स, टर्पिन्स व फिनॉल्स) गुंतागुंतीच्या मिश्रणाने बनलेली असतात.
गंधचिकित्सेतील प्रत्येक तेलाचे स्वतःचे वैशिष्ट्यपूर्ण गुणधर्म असतात. बहुतांश तेले जंतुनाशक असतात, मज्जासंस्थेला शांत करतात किंवा वेदना शमवतात. ही तेले नेहमी सौम्य करून त्वचेवर लावली जातात अथवा नाकाने हुंगली जातात. काही तज्ज्ञ ते तोंडावाटे घेण्याचा सल्ला देतात; परंतु योग्य प्रशिक्षित वनौषधी तज्ज्ञ (Qualified herbalist) किंवा वैद्यकाच्या सल्ल्याशिवाय त्याचे सेवन करू नये. बाह्य लेप आणि हुंगणे या पद्धती सेवनापेक्षा जलद आणि प्रभावी मानल्या जातात. चूळ भरणे किंवा गुळण्या करणेही गिळले नाही तर सुरक्षित असते.
अत्यावश्यक तेले त्वचेतून त्वरित झिरपून रक्तप्रवाहात मिसळतात आणि शीघ्र परिणाम करतात. क्लिनिकल चाचण्या दर्शवतात की अत्यावश्यक तेले त्वचेपेक्षा किंवा सेवनापेक्षा नाकावाटे हुंगल्याने (Inhalation) सर्वात वेगाने रक्तप्रवाहात पोहोचतात.
“सर्व इसेन्शियल तेलांची नावे ही त्यांच्या मूळ झाडाच्या नावावरून ठेवलेली असतात.” हे वाक्य _______

Read the following passage carefully and answer the questions based on it:
Aromatherapy, Essential Oils, Biological Chemistry & Therapeutic Inhalation Aromatherapy is the use of essential oils for their therapeutic properties. An essential oil is a highly odiferous substance found in particular aromatic plants. The oil usually bears the name of the plant from which it is derived (e.g. jasmine, lavender), though there are exceptions such as neroli, extracted from orange blossom. The oil is stored as microdroplets in tiny sacs or glands. Depending on the species, it is obtained from flowers, leaves, stems, roots, fruits, or resins via distillation. Essential oils are not greasy like vegetable oils (e.g. olive, corn, soya). They are light, volatile, and composed of complex organic chemical mixtures (acids, esters, alcohols, aldehydes, ketones, terpenes, phenols). Every essential oil has specific healing virtues, mostly possessing antiseptic, sedative, or anti-inflammatory properties. They are usually diluted and applied to the skin or inhaled. Ingestion is controversial; it is safer not to ingest essential oils unless directed by a qualified herbalist or medical practitioner. External application and inhalation are faster and safer than ingestion. Mouthwashes and gargles are also safe provided they are not swallowed. A key characteristic of essential oils is rapid penetration into the bloodstream. Clinical tests demonstrate that essential oils enter the bloodstream more quickly by inhalation than either transdermally (through the skin) or orally. “All essential oils are named after their plant of origin” - This statement is _______
