Ginger (Zingiber officinale (L.) Rosc) improves oxidative stress and trace elements status in patients with alopecia...

Alopecia areata (AA) involves oxidative reactions in the hair follicle. Its treatment is difficult due to both the unknown etiology and the adverse drug effects. Aims: This study aimed to evaluate the effects of orally administered ginger powder on the oxidative stress markers of the plasma and blood cells in Iraqi patients with AA.

Twenty patients (9 females and 11 males), with a mean age of 26.0 ± 8.0 years, with different lesions of stable alopecia areata localized on the scalp, were enrolled in this pilot study. Exclusion criteria include the use of any medication that may influence the course of the disease. All patients were treated with 500 mg of ginger powder once daily for 60zz days. Blood samples were obtained at zero time, day-30 and day-60 and utilized for the evaluation of the erythrocytes and lymphocytes contents of reduced glutathione (GSH), malondialdehyde (MDA) and total antioxidant status (TAS), in addition to the assessment of serum zinc (Zn) and copper (Cu) levels. The results are compared with those of 20 healthy subjects served as a control group.

Treatment of the AA patients with ginger significantly improves the antioxidant/oxidant balance of the erythrocytes and lymphocytes, which is known to be impaired in the patient group as compared with healthy subjects. The ginger powder also elevates the serum concentration of zinc up to that reported in controls and associated with normalizing serum copper levels at the end of the treatment period.

Consumption of ginger as a supplement by the patients with AA could improve the oxidant/antioxidant balance of the erythrocytes and lymphocytes and restoring the normal level of serum zinc.
