Herbs for Low White Blood Cell Count?

Is there an herb that could help raise the white blood cell count in your system?

The white blood cells play an important role in the immune system. A low white blood cell count can result from various conditions including infection including HIV and autoimmune diseases, chemotherapy or radiation treatment, and leukemia and other bone marrow problems. It is important to treat the underlying problem, and not just the symptom. Consultation with a holistic practitioner will give you a complete assessment with dietary and herbal recommendations suitable for your individual condition. Goal of therapy will likely be to support the immune system, support digestion and elimination as determined from the health evaluation, build the blood and treat the underlying condition.
Herbs used to increase the white blood cell count include: Guggul resin (Commiphora mukul), taken as a tincture or a powder; nettle, taken as a strong tea and echinacea taken as a tincture. Other supporting herbs include Astragalus to enhance the immune system and build rich blood, and dandelion root to protect the liver and the immune system and to improve digestion.
A diet to support the immune system is high in fresh fruits and vegetables and other whole foods, and low in fats, sugars, white flour products and food additives.
