Tomato (Fānqié 番茄)
This is another poisonous plant which contains solanine alkaloids, and is also a distant cousin of the potato, the deadly nightshade and the black nightshade. In the West, of course, it is very widely cultivated for its fruits. It has been said and written that tomatoes cause or encourage the growth of cancer, but there is as yet no definite proof of this assumption, although it has been proved in tests on animals that they can cause gastro-enteritis, apathy, nervous complaints, and other illnesses of various kinds. In our ancient Chinese medicine, the whole plant is used, but any dosages that are given are always in very small quantities. It is used to fight against excess toxification in the stomach, enlarged thyroid glands, feverish attacks of all kinds, and also leucorrhoea.
