The seeds are used in griping colic pain in Kalahandi area of Orissa state whereas, the aerial parts possess antinociceptive, anti- inflammatory and diuretic properties. Roots are used as an astringent and cooling remedy. Decoction of leaves and shoots is used as a stimulating wash for ulcers, acting as a good healer of the scarred tissue. A paste of the root is used externally in the treatment of scabies. (Source: Kirtikar and Basu, 1935 and others).

Can someone plz give the ID?
Polygonum barbatum !
Now Persicaria barbata (L.) Hara (syn: Polygonum barbatum L.)
Hooghly : Polygonum serrulatum Lagasc. ; Boiss . Fl. Orient. iv. 1028? (FBI.v.38) ? : 8 posts by 3 authors. Attachments (4).
This is common, possibly annual, in ditches or marshes.
Leaves subseesile, may be cordate, margin possibly serrulate (or with stiff hairs?) as can be seen in the 4th pic.; ochreal cilia equal to tube length.
Yes, I think the ID is correct.
Thanks for this post. I think you need to recheck the ID for this plant.
The Plant List mentions Persicaria decipiens (R.Br.) K.L. Wilson as the accepted name for Polygonum serrulatum Lag.
Moreover, your photos do not match with the images available on net:
Missed your feedback yesterday, didn’t receive email. Yes, I have seen the accepted name in The Plant List. But, I have deliberately used the name/entry in FBI or Bengal Plants or in Botany of Bihar and Orissa for reason I will explain eventually.
“Perianth color is variable and taxonomically less important (atleast in Persicaria)”
I think I can ignore what FoZ shows or displays. Please note :
I agree that it doesn’t look like the one in FoZ, but at the same time neither the other uploads in eFI, except one which is not clear, looks like the one in FoZ !!!
There is an interesting account, on Polygonum serrulatum Lagasc., in Haines.
FoP has its say – http://www.efloras.org/florataxon.aspx?flora_id=5&taxon_id=242100108.
Perhaps, as FoP says, following taxa also need to be taken account of –
There is ample provision to get confused by the descriptions in the above links.
However, attached here some more photographs, that I think of the same plant species, recorded elsewhere in some other time.
The ID is wrong. A doc can be found on Indian species – http://www.cibtech.org/J%20Plant%20Sciences/PUBLICATIONS/2014/Vol-3-No-2/JPS-018-013-SRIVASTAVA-FAMILY-INDIA.pdf
After all the discussion I think it should be Persicaria longiseta
Persicaria barbata (L.) H. Hara ??
Yes, appears more closer as per images at Persicaria barbata
