A systematic review of scientific experimentation addressing olfactory effects on mood, physiology and behavior was undertaken. From this review, 18 studies meeting stringent empirical criteria were then analyzed in detail and it was found that credible evidence that odors can affect mood, physiology and behavior exists. To explain these effects, pharmacological and psychological mechanisms were explored and a psychological interpretation of the data was found to be more comprehensive… 
Differential effects of lavender and rosemary on arousal and cognitive performance
This study assessed the impact of the essential oils of lavender and rosemary on cognitive performance, mood, and physiology in normal adults. Ninety participants were assigned to either one of the

TLDR
Through the experimentally validated mechanisms of odor-associative learning and the privileged neuroanatomical relationship that exists between olfaction and the neural substrates of emotion, odors can be harnessed to induce emotional and physiological responses that can improve human health and wellbeing.

TLDR
The observable aroma effects were produced by a combination of mechanisms involving aroma-specific pharmacologic properties, aroma hedonic properties, and participant expectations, and in the future, each of these mechanisms could be manipulated to produce optimal functioning.
Depression, Olfaction, and Quality of Life: A Mutual Relationship
TLDR
The links between olfactory processing, depression, and quality of life, and olfaction is an innovative research field that may constitute a new therapeutic tool for the treatment of depression.
Physiological, cognitive, and expectancy effects of aromatherapy following acute stress
Objective. Aromatherapy is commonly used for stress relief, yet the evidence for its effectiveness is weak due to the poor quality of previous studies and lack of understanding for the aromatherapy

Effects of the odorant Hedione on the human stress response
TLDR
Evidence is provided for a modulation of the human response to acute psychosocial stress by Hedione through binding to the VN1R1 receptor, which is expressed on the human nasal mucosa.

Emotional Responses Evoked by Dental Odors: An Evaluation from Autonomic Parameters
TLDR
The results suggest that eugenol can be responsible for different emotional states, depending on the unpleasantness of the subjects' dental experience, and seems to confirm the role of odors as elicitors of emotional memories.

Sedative effects of the jasmine tea odor and (R)-(−)-linalool, one of its major odor components, on autonomic nerve activity and mood states
TLDR
The low intensity of jasmine tea odor has sedative effects on both autonomic nerve activity and mood states, and (R)-(−)-linalool, one of its components, can mimic these effects.
Emotional qualities of odors and their influence on the startle reflex in humans.
TLDR
Evaluating the emotional effects of positive and negative odorant stimuli found that H2S, a presumed negative foreground stimulus, significantly enhanced the startle-reflex amplitude relative to neutral air stimulation, whereas vanillin, a positive foreground stimuli, tended to reduce the reflex amplitude compared withneutral air stimulation.
Olfaction, Emotion and Associative Learning: Effects on Motivated Behavior
TLDR
It is suggested that odors readily become associated to emotions and can thereby influence behavior and are compatible with the conclusion that decreased time spent by participants in the negative-same-odor condition was due to emotions elicited by associative learning to the ambient odor.
