Curcuma longa is a perennial herb belongs to family Zingiberaceae
and is cultivated extensively in Asian countries. The rhizome is used medicinally as a yellow powder which is used as a flavor in many
cuisines and as a medicine to treat many diseases like flatulence, jaundice, menstrual difficulties, hematuria, hemorrhage, and applied as an ointment to treat many skin diseases. The present research study
was conducted to know the toxicity nature of heavy metals in plant
patrts of Curcuma longa and its remediation. Pot culture experiments were conducted with three treatments till productivity levels at
Greenhouse of Botanical Garden, Department of Botany, Osmania University, Hyderabad.The three treatments consists of Treatment I
control without any addition of heavy metals to the soil, Treatment II - heavy metals spiked into the soil and Treatment. III, 1 % of Calcium Hydroxide added along with heavy metals to
the soil . The results showed in when compared to control that Ca (OH) 2. In treatment II the high concentrations of heavy metals (Ni, Cd and Cr) are found in leaf and rhizome of Curcuma longa when compared with 1% Calcium hydroxide treated soil in (Treatment III).
In addition, the plants grown in 1% Calcium hydroxide treated soil , reversed the growth
suppression and inhibited the heavy metal toxicity in plants as evidenced by reduced heavy metal concentration plant parts. The study concludes that medicinal plant Curcuma longa affected with heavy metals can be treated by using 1% calcium hydroxide.
