There are numerous medicinal plants in current use in Thailand.
Ayurvedic medicine and Thai traditional
medicine, each finding many uses and deserving to be exhibited to the
enthusiasts who wish to know about the characteristics of its stem, flower,
fruit together with the research work undertaken, it is impossible to
exhibit all, or even the majority, of them. For this reason some common
medicinal plants which received research attention both locally and
internationally have been selected. In addition, some which
have so far attracted little attention from
researchers have also been included owing to their recognition in
Ayurvedic Medicine and traditional medicine in Thailand
as well as some Asian countries.
The information
has been
searched from the literature, selected and edited in order to be presented in
this site, which will familiarize the reader with general characters of such plants. No botanical details are given
owing to the nature of this
work and also to limited space. Sketches of the plants, however, are
given to enable the reader to recognize them. It should be noted that
all Thai, Sanskrit, Latin and English common names of the plants
appearing in this site are transliterated into English with the sound in
mind, and not according to the official rules. In addition, owing to
the limited space the traditional
usage of each plant is meant to be representative, and by no means comprehensive.

of the Ayurvedic Pharmacopoeia. Chemically, it is red sulphide
of mercury and gold in uncombined form. It is a sublimed product
made from pure mercury, sulphur and gold.
Eight parts of mercury and one part of gold leaf
are mixed together to form an amalgam. To this mixture 16 parts
of sublimed sulphur are added and the resulting mixture is
ground very thoroughly in a stone mortar for 24 hr. or more
until the whole is converted to a lusterless, fine, impalpable
powder of uniform consistence. This mixture is then placed in a
narrow mouthed bottle and is gradually heated on a sand bath. On
heating, the bottle is filled with reddish fumes of various
hues. On cooling Makaradhvaja is found deposited in the inner
surface of the neck of the bottle.
It is seldom used alone. In the majority of
cases, it is mixed with various drugs called ‘anupana’ or
adjuvants. In cases of indigestion and diarrhea, Makaradhvaja is
mixed with powdered bael fruit (Aegle marmelos); in cases of
fever and cough it is given with the juices of ginger, betel
(Piper betel) and tulsi leaves (Ocimum tenuiflorum). Generally,
honey is used in the absence of proper adjuvants. The medicine

regulated according to age. Makaradhvaja, when taken regularly,
