Herbal medicine and its dangers

I newly heard a talk by Thomas Efferth of the Institute with regard to Pharmacology of the University of Mainz put ~ herbal medicine. There is a used by all point of view that substances derived from plants are innocuous and good while the chemical drugs of pennon medicine are evil. The speaker emphasized that plants desire good reasons for not being welfare to those who eat them. They chouse not have immune systems of the protoplast we do and they cannot trip away and so it is regular that they use poisons to secure from attack. themselves. Herbal medicines are effective in some cases but they need to exist subject to controls as much because do substances obtained by artificial chemical way. In the talk a number of examples of the dangers of ‘natural’ medicines were presented and I be disposed write about some of them in the present state.

The first example is that of Aristolochia. This a extensive genus of plants, some of that are poisonous. One of these, Aristolochia clematitis, has been extensively used in pertaining medicine. It was used extensively in the occident in ancient times and is used in traditive Chinese medicine until today. In the report the story was told of every incident which happened in Belgium. There was a fruits sold as a means of loss weight which contained a Chinese fix. It sold so well that the manufacturer’s supplies of the plant were running gone ~. When more was ordered a fateful mistaking took place. There are two plants that have the same name in China. The any is that which was originally contained in the make heavyloss product. The other is the venomous Aristolochia fangchi and it was the human being which was delivered. This led to greater degree of than 100 cases of kidney failure in the the million using the product. Another way in which plants can be dangerous is similar to weeds in crop fields. In the Balkans abomination of grain with Aristolochia clematitis led to a kidney illness called Balkan nephropathy, with 35000 recorded cases. The meaning, aristolochic acid, which is responsible in the place of the kidney toxicity is also known to have existence a strong carcinogen. Interestingly, this pith is not poisonous for everyone and its ill-qualified effects depend a lot on the variability in liver enzymes among individuals.

A class of substances used ~ means of many plants to protect themselves over ~ insects are the pyrrolizidine alkaloids. These substances are hepatotoxic and carcinogenic. They may influence through the food chain being mould, for instance, in honey. It has been remarkable that there may be risks associated to the footing up of these substances contained in medical herbs used both in the West and in China. It was mentioned in the talk that drinking too much of real types of herbal tea may have ~ing damaging to health. The problem is usually not the plants that are the important components of the teas but other plants what one. may be harvested with them in dull quantities. There is at least common exception to this, namely coltsfoot (Tussilago farfara). In human being case the death of an suckling due to liver disease is believed to have existence due to the mother drinking this stamp of tea during pregnancy. After that the opportunity to sell of coltsfoot was banned in Germany.

There were some remarks in the talk on heavy metals which I found quite suprising. One concerned ayurvedic remedial agent which has an aura of core gentle and harmless. In fact in great number of these substances certain heavy metals are added delibrately (guide , mercury and arsenic). According to Wikipedia other than 80 cases of lead poisoning appropriate to ayurvedic ‘medicines’ have been recorded. Another comment was that there can be important concentrations of heavy metals in tobacco effluvium. The negative health effects of smoking are sufficiently well known however this aspect was new to me.

Another thesis in the talk was interactions between herbal medicines and normal drugs. Apparently it is ~times the case that patients who employment herbal remedies are afraid to cursory reference this to their doctors since they plot this may spoil the relationship to their practitioner. Then it have power to happen that a doctor is suprised ~ dint of. the fact that a drug he prescribes is not in operation as expected. Little does he know that the patient is secretly anger a ‘natural’ drug in resemblance. An example is St. John’s wort what one. is sometimes taken as a restoration for depression. It may work and it has nay direct negative effects but it be able to be problematic because it reduces the personal estate of other drugs taken at the same time, e.g. the contraceptive pill. It changes the etc. of liver enzymes and causes them to get rid of other drugs from the body faster than would normally take place, thus causing an effective reduction of the drench.

We are surrounded by poisonous plants. I was at all times sceptical of the positive effects of ‘natural’, put in seed-derived medicines. Now I have realised for what cause seriously the dangers of these substances should be taken.
