TURMERIC HITS NEEMDIRECT!

Turmeric is a common ingredient of traditional oriental medicine for use as a stomach tonic and blood purifier, and was used for a variety of skin conditions and minor injuries. Today, turmeric is considered potentially beneficial for use in connection with symptoms associated with a variety of health conditions due to its purported antioxidant, anti-tumor, anti-inflammatory, and antibacterial effects.



The active constituent in turmeric is known as curcumin, which is believed to be responsible for the following medicinal and therapeutic properties:

  • Acts as anti-inflammatory by lowering histamine levels
  • Acts as anti-oxidant protecting against free radical damage
  • Protects liver from certain toxins
  • Improves circulation by inhibiting blood platelets from sticking together
