Extract taken from The Encyclopaedia of Natural Medicine (Michael T Murray 3rd Edition ). Sulphasalazine is a powerful immune suppressant used against auto immune diseases such as rheumatoid arthritis and Crohns Disease (referred to CD in this article).
I also copy and paste an extract on the chapter of Frankincense from Medicine of the Prophet (Al Jawziyyah)...
‘Luban is hot in the second degree and dry in the first degree. It is also a mild constipation agent. It is very benecial and its side effects are minimal. Among the benefits of the Luban is that it stops and heals bleeding, stomach ache, diarrhea, helps digest the food, gets rid of flatulence, cures eye sores, helps the body grow esh on most ulcers and strengthens the weak stomach. Luban also dries the phlegm and the moistures accumulating in the chest, cures eyesight impairment and prevents malignant sores from progressing.
When Luban is chewed alone or mixed with Persian thyme, it will provoke phlegm, release and relax the tongue muscles and help the mind become sharper. When the Luban is burnt, it helps cure some illnesses and makes the air smell fresh’.
