About Guam leaf
The Guam leaf is a members-only Herblore supply in Old School RuneScape.
"A bitter green herb"
Over the last 30 days it traded between 305 and 515 gp on the Grand Exchange, averaging 356 gp. About 183,426 units changed hands per day. The price is down 23.3% across that window. The Grand Exchange buy limit is 13,000 every 4 hours. Selling one at the average price costs 7 gp in Grand Exchange tax.
Casting High Level Alchemy returns 1 gp, which is 99.7% below the 30-day average price, so alching a bought one loses money.
