About Grimy guam leaf
The Grimy guam leaf is a members-only Herblore supply in Old School RuneScape.
"It needs cleaning"
Over the last 30 days it traded between 243 and 341 gp on the Grand Exchange, averaging 288 gp. About 157,982 units changed hands per day. The price is down 6.4% across that window. The Grand Exchange buy limit is 13,000 every 4 hours. Selling one at the average price costs 5 gp in Grand Exchange tax.
Casting High Level Alchemy returns 7 gp, which is 97.6% below the 30-day average price, so alching a bought one loses money.
