These include ordinary wheal and flare reactions and mosquito bite allergies (MBA). Wheal Anna Maria, Wheal Fanny, Wheal Emma and Wheal Josiah among them. The mine was originally called Wheal Maria, then changed to Wheal Eliza. The wheal that develops from the glycerinated extract drop is compared against the saline control.

Other archaic English forms include "wal, wale, whal, whalle, whaille, wheal", etc. By 1792 a branch from Poldice extended to Wheal Unity. The South Wheal Towan copper mine also operated in the area. The CD pressings included the extra tracks "Hellraiser" and "The Wheal". The last phase was the production of a wheal filled fluid over the original spot. Operational by 1808, smelting was also performed at Wheal Lushington.
