Elevated CO2 enriches Ginger Varieties


 Hot spicy news!

Ali Ghasemzadeh and Hawa Z. E. Jaafar have been studying ginger and have compared plants under 400ppmv CO2 and doubled to 800ppmv. The two Malaysian researchers report that the antioxidant activities of the leaf and rhizome extracts were "increased significantly" by the elevated atmospheric CO2 concentration.

From CO2 Science:

What it means
Ghasemzadeh and Jaafar conclude their paper by stating that their results suggest that "enriched ginger varieties by elevated CO2 concentration could be employed in ethno-medicine for the management of breast cancerous diseases." But they indicate that "more focused clinical studies are necessary to establish whether these varieties can be exploited to reach cancer blocking or remedial effects in the human body."
