Nowadays, use of alternative and complementary therapies with mainstream medicine has gained the momentum. Aromatherapy is one of the complementary therapies which use essential oils as the major therapeutic agents to treat several diseases. The essential or volatile oils are extracted from the flowers, barks, stem, leaves, roots, fruits and other parts of the plant by various methods. It came into existence after the scientists deciphered the antiseptic and skin permeability properties of essential oils. Inhalation, local application and baths are the major methods used in aromatherapy that utilize these oils to penetrate the human skin surface with marked aura. Once the oils are in the system, they remodulate themselves and work in a friendly manner at the site of malfunction or at the affected area. This type of therapy utilizes various permutation and combinations to get relief from numerous ailments like depression, indigestion, headache, insomnia, muscular pain, respiratory problems, skin ailments, swollen joints, urine associated complications etc. The essential oils are found to be more beneficial when other aspects of life and diet are given due consideration. This review explores the information available in the literature regarding therapeutic, medical, cosmetic, psychological, olfactory, massage aromatherapy, safety issues and different plants used in aromatherapy. All the available information was compiled from electronic databases such as Academic Journals, Ethnobotany, Google Scholar, PubM ed, Science Direct, Web of Science, and library search.

Doxorubicin is a commonly used anticancer agent, which may cause cardiac toxicity. The present study designed to evaluate Phoenix dactylofera (dates) in doxorubicin (DXR) induced cardiac toxicity and cardiac remodeling in Wistar albino rats. The experimental rats procured, acclimatized and finally divided into five groups (n = 6). Group I served as normal controls, group II served as disease controls and groups 3, 4 & 5 served as therapeutic groups (Phoenix dactylofera 5%, 10%, and 15% respectively). Cardiac remodeling and toxicity in the rats were induced by administration of DXR (1.25 mg/kg i.p. in 16 divided doses/month). At the end of protocol, effect of Phoenix dactylofera on cardiac remodeling was evaluated by measuring parameters like haemodynamics, heart weight, anatomy, Troponin T, creatine phosphokinase (CPK), creatine phosphokinase-MB (CPK-MB), Lactate dehydrogenase (LDH), serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), calcium ion Ca2+, sodium ion Na+, potassium ion K+, intracellular enzymes like Malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT). The disease control groups showed significantly elevated (p dactylofera significantly (p 2+, Na+, K+ levels to a normal value. Further, the histological studies of the cardiac tissues demonstrated that the normal architecture of the cardiac cells was restored in the animals fed with dietary Phoenix dactylofera as compared to disease controls. The findings show that the administration of Phoenix dactylofera has the potential to prevent the toxicity induced by doxorubicin in the experimental rats.
