Treating Depression with Saffron: Benefits and Side Effects

If people for a relatively long period of time are no longer energetic and willing to do routine tasks like in the past, they need to consult a psychiatrist. In today’s fast-paced and stressful world, sometimes we all may lose our interest in the daily activities we used to do at home or at work for a short period of time, or we may feel sad, but if this disinterest and sadness continue more than two weeks, possibly we face a mental illness: depression. Various studies confirm the positive curative effect of saffron supplementation on symptoms of mild-to-moderate depression with fewer adverse events compared to conventional antidepressant medication.

Against a growing problem

Depression as a mental disorder (also called major depression, major depressive disorder, or clinical depression) is classified as a mood disorder.Around 5% of the world’s population is diagnosed with depression. Researchers believe that actual figures are higher ( around 20%) as today, there are many reports on mood disorder cases.

Incompatibility between past human surroundings and modern-day living paves the way for the growing chronic diseases that, in turn, may be fundamental to ascending rates of depression. On the other hand, a declining social trust and widening gaps of inequality plus loneliness in our crowded cities are underpinnings of a depressiogenic social context. A glance at modern populations reveals that most of them are overfed, malnourished, sedentary, sunlight-deficient, sleep-deprived, and socially isolated. These modifications in lifestyle each contribute to various physical disorders and affect the occurance and therapy of depression.

Antidepressant medication, psychotherapy, or both are proposed to be implemented to deal with depression. Electroconvulsive therapy and somatic treatments are also used to address this rampant disorder. Does traditional medicine suggest any drugs to treat depression? The eye-catching efficacy of saffron in harnessing depression is mentioned in traditional medicine resources.

Symptoms of depression

Feeling sad, losing interest in daily activities, alteration in appetite (increase or decrease in appetite), change in sleep hours, increasing fatigue, feeling worthless or guilt, lack of concentration or decision-making, and in acute situations, the desire to die or commit suicide are signs that can be considered as symptoms of depression, especially if these feelings exist in you for a long time.

If people for a relatively long period of time are no longer energetic and willing to do routine tasks like in the past, they need to consult a psychiatrist. In today’s fast-paced and stressful world, sometimes we all may lose our interest in the daily activities we used to do at home or at work for a short period of time, or we may feel sad, but if this disinterest and sadness continue more than 2 weeks, possibly we face a mental illness: depression.

Due to its severity and weakness, depression can also lead to physical diseases like thyroid problems, brain tumors, and vitamin deficiency. So, if you have such troubles continuously, they could be counted as symptoms of depression.

Seasonal depression

One of the most common types of depression is seasonal depressive disorder, which starts at the beginning of the season and is the most common in winter. Lack of natural light affects the part of the brain that is responsible for sleep and appetite, mood, libido, and activity level.

As the days get shorter and as a result, the colder and the humidity increases, a large number of people feel depressed. These people feel that they have less energy.

According to the BBC, about two million people in the UK suffer from seasonal depression disorder, which is also known as “winter depression” due to its exacerbation in the cold season. In this way, for example, if it is October and you feel anxious, you cry all the time and eat too much, and you don’t want to socialize with others and like to stay in your bed and don’t go out, you are probably dealing with this type of depression.

less adverse effects of plant extracts

Depressive disorder is one of the most prevalent psychiatric diseases and Murray and Lopez estimated that more than 21% of the world’s population are suffering from it.

Side effects of taking synthetic antidepressant drugs such as the inability to drive a car, dry mouth, constipation, and libido make the majority of patients reluctant to take these drugs in their appropriate way. That is why most sufferers prefer plant extracts, and it is proved that these attractive sources of drugs produce a better result with much lower side effects in the treatment of depression. For example, people who take fluoxetine as a conventional antidepressant experience side effects like losing their appetite, weight loss (which could be a severe problem for thin people), nervousness, anxiety, restlessness, poor concentration, and feeling tense. Another complaint is sexual dysfunction (including difficulty maintaining an erection).

Taking imipramine as another common antidepressant may lead to a wide range of side effects like nausea, drowsiness, weakness or tiredness, excitement or anxiety, nightmares, dry mouth, and skin more sensitive to sunlight than usual. Also, changes in appetite or weight, constipation, difficulty in urinating or frequent urination, changes in sex drive or ability, and finally, excessive sweating are reported by patients who took the drug.

In some people, the drug can even have more severe side effects such as spasms in jaw, neck, and back muscles, slow or difficult speech, shuffling walk, uncontrollable shaking of a part of the body, fever, sore throat, or other signs of infection, difficulty in breathing or swallowing, severe rash, yellowing of the skin or eyes, and irregular heartbeat.

Rare compounds in saffron

The red stigmata of this spice contain different rare bioactive compounds including, safranal, crocin, campherol, picrocrocin, crocetin, α- and β-carotenes. These picrocrocin and crocin only isfound in saffron and gardenia.

This rareness and the majical effect of such compounds make saffron the subject of a large number of research papers focusing on potential saffraon role in controlling or treating cancer, degenerative eye deseases, and neurodegenerative disorders. Studies have confirmed the antioxidant and anti-inflammatory role of ethanol or aqueous extracts of saffron, safranal, and crocin. Another study reported a reduction of blood bilirubin level and decreased blood cholesterol, and triglycerides were found after using crocetin and crocin. Since one of the things agreed upon by scientists about saffron is its efficacy on  the treatment of depression, and a lot of research has been done on this matter, we will examine depression below.

A double-blind, placebo-controlled study shows that saffron aqueous extract and its main constituent, crocin, on health-related quality of life, depression, and sexual desire in coronary artery disease patients.

Aqueous extract of saffron increases brain dopamine and glutamate concentrations in rats. Saffron aqueous extract and its constituent crocin reduce stress-induced anorexia in mice.

The antidepressant effect of Crocus sativus aqueous extract and its positive effect on increasing some protein levels in rat hippocampus is also proven.

In human brain

Preclinical studies has demonstrated an anxiolytic effect of saffron in patients with mild to moderate depression.

By comparing the effects of saffron to other pharmacological treatments of depression, we can say that it may act on similar neurotransmitter systems, although we need deeper studies to discover the exact mechanisms of action of saffron components on the human brain.

In fact, saffron enhance brain function, in particular, in two distinctive way: As brain-derived neurotrophic factor (BDNF), Nerve Growth Factor cAMP, and Response Binding protein (CREB) are important players in controlling anxiety and depression, saffron has a notable effect on those factors and protein levels in the brain.

Researchers at Murdoch University conducted a systematic analysis of every clinical trial they could find for high-quality, randomized, double-blind studies using Saffron and concluded that clinical trials support the use of Saffron for the treatment of mild to moderate depression.

By spurring the release of anandamide and arachidonoylglycerol which are also released after using marijuana in our body, saffron reduces depressive symptoms without any negative adverse effects of marijuana.
