Sickle cell disease (SCD) is an inherited problem that causes the shape of some red blood cells (RBCs) to change to a sickle shape. The sickle RBCs can block blood flow. This can slow or stop the flow of blood and oxygen to tissues and organs. The body will destroy the sickle RBCs because they are not normal. This means a person has fewer overall RBCs. This causes anemia, which makes it harder for the body to get oxygen.

There is no cure. SCD is managed with lifestyle changes and medicine. Blood transfusions or stem cell transplantation may also be needed. Some people turn to natural therapies to help manage related problems.

Natural Therapies

May Be Effective

These therapies may provide benefit:

  • Cajanus cajan (pigeon pea) is a legume. K1
  • Fish oil is a fat that is extracted from fish tissue. B1-B3
  • Lime juice D1
  • NIPRISAN is an herbal mixture from Nigeria C1, C2
  • Yoga uses body poses and breathing to improve health. G1
  • Zinc is a nutrient that helps the immune system. A1

Unlikely to Be Effective

Magnesium is a nutrient that is needed for many processes in the body. It is unlikely to provide benefit to people with SCD. E1

Herbs and Supplements to Be Used With Caution

Talk to your doctor about all herbs or supplements you are taking. Some may interact with your treatment plan or health conditions. Some supplements discussed here have certain concerns such as:

  • Zinc can be toxic in high doses. This can lead to copper deficiency and problems with the immune system, heart, and anemia.
