292 A Treatise on 
Another Sort of Manna is ufed in the Eafterfl 
Countries, which is an Exudation from a fmall 
thorny Shrub, named Alhagi Maurorum , Rauvolf. 
Hi ft. Ludg. 94. Genifta-Spartium Spinofum , foliis Po- 
lygon: , C. B. P. 394. It grows plentifully in Egypt , 
Armenia , Georgia , Perfia , about Mount Ararat , and 
in fome Iflands of the Archipelago. It is often found 
twifted about with Dodder. The whole Plant has 
an aftringent Tafte; and fometimes in Egypt^ ac- 
cording to Auguftin Lippi , it lets fall a red aftrin- 
gent Tear, like Dragon’s Blood. 
Rauvolfius and Tournefort tell us that upon its 
Leaves, Stalks and Branches, efpecially in Perfia , 
the People colledt Manna, which they term Trun* 
fchibin , and the Arabians Tereniabin and Trungibin. 
In the hotter Months of the Summer it breaks forth 
in Drops, which harden into reddifh Grains of the 
Bignefs of Coriander-Seed. Thefe, when gathered, 
are compared into a large Lump, with a Mixture 
of Leaves, Thorns, &c. If it were entirely pure, 
it would be no lefs efficacious than Calabrian Manna : 
But the Inhabitants give it to Jiij. for a Dofe ; be- 
caufe it ufually confifts of a greater Proportion of 
Leaves than Juice. 
The renowned Tournefort makes no Doubt but that 
this is the Tereniabin of Serapio and Avicenna , which, 
according to their Accounts, was a Manna of the fame 
kind, defcending from the Heavens, like Dew, 
upon certain thorny Shrubs.
