For these symptoms use Lily Preserve Metal Formula. Use with caution in hypertensive patients. If this occurs do not take before bedtime. Therefore we have no choice but to take precautionary actions to protect patients' health, and remove Xi Xin for internal use in our pharmacopeia. Although human toxicity levels for aristolochic acid have yet to be established, we feel that only products that test negative for this substance should be consumed.
Safety is our first priority.
Since aristolochic acid content seems to be affected by preparation method and species selection we are hopeful we will soon be able to provide Xi Xin products that have no detectable level of this substance. These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.
