The wu lou is known in English as a "bottle gourd" or "calabash".
Ancient Taoist “magicians” carried powerful healing potions inside large wu lous. The wu lou itself is believed to have healing powers.
The wu lou can be placed
or hung near the bedside, where it helps with health and healing.
It can be placed or hung anywhere in the home or vehicle for protection and to deflect negativity.
Since these are natural wu lous, the size and shape may vary substantially. These average approximately 4"-5" in height, not including the stem.
