The effects of stress, environmental toxins and poor eating habits may have a lingering effect on the body, energy system and mood. The body; the liver, kidneys, lymphatic and digestive systems, may need extra help clearing out the accumulation of toxins left behind. The symptoms of a toxic and sluggish system include fatigue, brain fog, sinus congestion, headaches, swollen lymph nodes, poor circulation, itching, allergies, bloating, swelling, constipation, acne, fluid retention and insomnia.
