If you bring up fungus, she is right back at you with downy mildew, white rot and purple blotch. Open your mouth and she will hit you with pink root, neck rot and basal rot. It's a wonder there are any onions at all. Personally, my hygiene routine has protected me so far from aster yellows and onion smut. Alas, the juries are out.
Some studies show garlic lowering blood pressure by small amounts.
Other studies show nothing of the kind. Several meta-analyses have looked at garlic and blood pressure, some finding a small but significant reduction on both systolic and diastolic blood pressures. Others find nothing. Everyone agrees it would be nice to do a few more studies with more people and better controls. By about 10 percent.
