Conclusions
The importance of Loureiro’s botanical studies may be summarized as
follows:
1) They are among the pioneering ethno-botanical studies in China made
by Westerns and have contributed to the progress of botany in general
and of Chinese botany in particular;
2) Through herbaria, drawings and written descriptions, he made known to
Europe for the first time many Chinese plants and promoted the transfer
of some plants from China to Europe;
3) Having corresponded with Western botanists Loureiro played an
important role in the West-East scientific exchange in the 18th century in
the field of botany;
4) The medicinal and several other uses of many plants were made known
to Europe;
5) In comparing the medicinal properties of plants as given in Flora;
Cochinchinensis and as given in Bencao Gangmu differences are seen
mostly due to different ideas on their applications and also due to
differences on the medicinal knowledge in China and in Europe;
6) Loureiro’s studies should be seen in the framework of the European
Enlightment and also in the framework of the physiocratic ideas
prevailing at the time.
