• Psychological factors are paramount, but as already hinted at these are not herbal issues.
• Food irritants. There is increasing evidence that chemical irritants have a role in this problem. They may be pollutants (such as heavy metals)or artificial food additives (such as colorings or flavors).

The herbal contribution is in two areas, calming the nervous system and helping the liver detoxify.

Herbs to consider in supporting a broad treatment plan. that must also include dietary and psychological aspects, might be:

Trifolium pratense (Red Clover)
Tilia spp. (Linden Blossom)
Matricaria recutita (Chamomile)
Carduus marianum (Milk Thistle)
