The benefits of saffron may include:
The majority of the health claims surrounding saffron relate to its high levels of specific antioxidants.
Other compounds include kaempferol and crocetin.
These antioxidants help fight against oxidative stress and free radicals in the body.
Preventing nervous system disorders
The antioxidants in saffron may play a role in protecting the body from disorders affecting the nervous system.
A study in the journal Antioxidants noted that saffron might theoretically help with Alzheimer’s symptoms due to both its memory-enhancing properties and its antioxidant and anti-inflammatory effects.
People with mild-to-moderate Alzheimer’s who took saffron for 22 weeks had cognitive improvements that were comparable with those of people who took the drug donepezil, and they also experienced fewer side effects.
While this is early evidence to support the medicinal use of saffron, researchers suggested that future clinical trials could help back up these claims.
There is also growing evidence that saffron may help improve mood and be a useful addition to treatment for depression.
Although some people recommend using saffron as a complementary therapy for improving mood, it is too early to recommend it for treating depression symptoms.
Saffron may also increase sex drive and sexual function in both males and females.
Researchers reviewed the effects of saffron on male infertility problems and noted that while it had a positive effect on erectile dysfunction and overall sex drive, it did not change the viability of the semen.
Women who took 30 mg of saffron each day for 4 weeks had increased sexual desire and vaginal lubrication compared with those who took a placebo instead.
Reducing PMS symptoms
Saffron may also act to reduce the symptoms of premenstrual syndrome (PMS).
The authors of a 2015 review looked at the research on saffron and symptoms of PMS. Women between the ages of 20 and 45 years who took 30 mg of saffron each day had fewer symptoms than those who took a placebo.
Additionally, women who simply smelled saffron for 20 minutes had lower levels of the stress hormone cortisol in their system, which may also contribute to a reduction in PMS symptoms.
Promoting weight loss
There is also some evidence to suggest that saffron may help promote weight loss and curb the appetite.
A study in the Journal of Cardiovascular and Thoracic Research found that taking a saffron extract helped people with coronary artery disease reduce their body mass index (BMI), total fat mass, and waist circumference.
People who took the supplement also had a reduced appetite compared with those in the placebo group.
