About Swamp weed
The Swamp weed is a members-only item in Old School RuneScape.
"Swamp weed found in the caves near Dorgesh-Kaan"
Over the last 30 days it traded between 209 and 1,796 gp on the Grand Exchange, averaging 487 gp. About 1,236 units changed hands per day. The price is down 85.9% across that window. The Grand Exchange buy limit is 13,000 every 4 hours. Selling one at the average price costs 9 gp in Grand Exchange tax.
Casting High Level Alchemy returns 1 gp, which is 99.8% below the 30-day average price, so alching a bought one loses money.
