In Medicine…

Crocus is a rare, pure and natural product that keeps the human body in excellent physical condition, with purity of spirit and increased physical and mental activities. It is a product of global interest and a wide use in many fields of science because there are no artificial substitutes for the plant and its stigmas. Many efforts have been made to find other natural products that possess these properties.

Because of its analgesic and soothing properties, saffron has been used since antiquity for food for its flavor, aroma and coloring properties, as well as for folk medicine for the treatment of certain diseases for centuries (Basker και Negbi, 1983).

The properties of the saffron could be utilized as a potential therapeutic agent for many diseases as evidenced by various biomedical studies

The interest in biological effects and possible medical applications of saffron has increased, especially those based on cytotoxic, anti-cancer and anti-neoplastic properties (Abdullaev, 2002.  Abdullaev and Espinosa-Aguirre, 2004.  Fernαndez, 2004.  Magesh et al., 2006.  Chryssanthi et al., 2009.  Dalezis et al., 2009)

The main biological activity of saffron is based on its high antioxidant capacity.

In fact, the antioxidant property of saffron is well known and widely studied, as this property is responsible for many of its biomedical features. The extracts of the saffron exhibit remarkable intracellular antioxidant activity by binding and purifying the toxic residues of peroxidation products

The antioxidant property of safflower is responsible for the prevention of many diseases whose mechanisms involve oxidation.

Thus saffron may be widely used in medicine in the following fields:


  • Suppressing the development of age-related harm (old age) (Farahmand SK, et al. 2013).,

Anti-inflammatory action

  • Prevention at the levels of inflammatory serum mediators (Byrami G, et al 2013).
  • Significant anti-inflammatory activity and could potentially be used as an anti-arthritic agent (Rabe SZT, et al, 2015).
  • Elimination of secondary complications associated with arthritis (Hemshekhar M, et al, 2012. Ding QH, et al 2013).

Wound healing, (Assimopoulou et al., 2005)

  • In the treatment of heat-induced burns, the saffron extract cream (20%) results in a significantly increased re-epithelialization that could be explained by the antioxidant effects of this spice (Khorasani et al., 2008)].

Anticancer and Antineoplastic Action

As a preventive and complementary therapy in various forms of tumor and cancer, it acts as a potent anticancer agent (Chryssanthi DG, et al. 2011), inhibits MDA-MB-231 cell penetration by reducing MMP expression, (Chryssanthi DG, et al. 2011), can regulate the inflammatory processes (Xu GL, et al., 2009) involved in the competitive effect of CSE in NMDA (Berger F, et al., 2011)..

It is a very promising chemotherapeutic and protective agent in the treatment of cancer.
