As long as it's not rubbish, it's all right. Filtered, it is not stagnant water. At most, it's good to let the black shell chew off the long white hair at first. The persimmon branches I put in the South American jar before didn't peel off, and they didn't smell after soaking for a year, but the bark soaked badly and peeled off when my fingers twisted. In fact, 90% of heavy wood in most families is directly used, such as purple pomelo and azalea.
