Happy herbs «Black cohosh helps
regulate oestrogen levels and provides symptomatic relief from hot flushes or vaginal dryness typically after two weeks,» says Leah Hechtman, president of NHAA.
But pollution also covers hundreds of chemicals which are fine or even beneficial at low
levels but which if released in large quantities or in problematic circumstances cause «harm» — like phosphorus (grows your veges but also leads to toxic cyanobacterial blooms which kill cattle), nitrogen (grows crops kills many native species of plants and promotes weed growth costing farmers), copper (used as an oxygen carrier by gastropods but in high concentrations kills the life in sediments which feed fish), hormones like
oestrogen (essential for
regulating bodies but in high concentrations confuse reproductive cycles especially with marine life) or maybe molasses from a sugar mill (good for rum but when dumped into east coast estuaries used to cause oxygen sag in estuaries leading to massive fish kills).
