Fragrance Does Relief Pain?!
Reverse Condition Reflexion Shows Odors Aids Pain Relief

In class, we have discussed about the concept of Condition Reflexion that turn a external stimulus into a predictor of dangerous. Recently, there is a research study about Condition Reflexion itself can also act as a reliever to pain. What determine the function of those condition reflexion stimulus? The answer is time.

Dr Ayse Yarali, of the university of wurzburg (Germany) discovered that fruit flies can develop a Pain Relief pattern when an odor is released right after a electrical shock. He found out that if they are using different odor before and after the electrical shock. one can act as an control and the other will become an reliever. After training, fruit flies will get clam very fast on 3 out of 5 tested organic odor. These reflexion does not affected by the flies' gender. What really matters is how soon the odor release after the shock present. Normally 8-40 seconds after the shock will get the best results.

Dr Yarali suggested that this relief pattern is either due to the psychological effect or a pathway on the neurobiology mechanism. These hypothesis still have rooms for further experiment to prove.

Will that be other organism also conduct these effects? Can we, human, perform these effects? Are our Fragrance's and scent's got the same abilities to aid pain/ stress relief? We dont have the answers. However this paper is a good start on such issue.

This is a very interesting idea, you often hear about strees-relief scents, and I always wondered if it had any scientific value. It would make sense that if a scent can be stress relieveing that it could be pain relieveing. I wonder if it ahs to do more with the conditioning than the actual properties of the smells though.

This is amazing! I would be thrilled if there was a natural scent that could relieve pain. I wonder what exactly it is about the smell that can rigger relief.I hope they do further study this to see if it has the same effect on humans.

wow this is a very interesting article. this make me think of how smells are very important in triggering memories. i think it must be the neurobiology of smell as suggested.

I would like to know what kind of fragrance he used. Are they made up of similar odors that are sold in shops for humans or totally synthetic odors?

Also, I know endorphins decreases the pain felt by individuals. I wonder whether fragrance have anything to do with endorphins being released.

How does they measure how calm a fruit fly is, and could they do this measurement in other animals?

What were the types of odors used in the experiment? Are they common odors or specific odors from certain organic chemicals? Did the odors that acted as controls at times became a reliever odor when used with a different combination of odors before and after an electric shock?

This makes a lot of sense considering that if you have pine freshener scents in the car or pine smells in hospitals, people seem to get better quicker and be calmer than if they were surrounded by the scent of death and antisceptic all of the time. Theodore Roosevelt said that the forests' rejuvinated him, so it's not uncommon that scents have the ability to calm and relieve the pain of other animals. My stomach is calmed by the smell of lime, so what kind of odor is used to give pain relief to these flies?

I believe that this experiment can help people who have pain in their body in daily life. I wish they can prove how good this experiment is. That way people can have a better relief without taking a medicine.

I enjoyed this article because we've learned in class, as I have in other classes, how powerful of a stimulus smell can be. It triggers different areas in the brain and if it could be used to relieve pain that would be incredible. I would like to know how they can take this idea and turn it into something tangible in the future.

I wonder if you could also cause anxiety by certain scents then? Have they tried this with any animals?
