The bottom of this page says that only these plants are good when used only when they are alive, and that DE doesnt help much either...


Natural antihelminticsExamples of naturally occurring anthelmintics include:

Tobacco (Nicotiana tabacum & Nicotiana rustica)[1]
Moringa oleifera (Moringaceae) (Micronutrient Powder)
Black walnut (Juglans nigra)
wormwood (Artemisia absynthium)
clove (Syzygium aromaticum)
tansy tea (Tanacetum vulgare)
Hagenia (Hagenia abyssinica)
Garlic (Allium sativum)
Diatomaceous Earth (DE)
Pineapple (Ananas comosus)
kalonji (Nigella sativa) seeds
male fern (Dryopteris filix-mas)
Monarda fistulosa (Wild Bergamot) [2]
Honey mixed with water and vinegar was also used as a vermifuge.
Plumeria (P. acutifolia or P. rubra) in Brazilian folk medicine.[3]
Peganum harmala[4]
Banisteriopsis caapi
genistein (from soy and other legumes)


It is important to note that much testing has been done and all evidence shows that these plants are only effective in their live state. Tested dried "Natural" de-wormers, as well as Diatomaceous Earth have consistently shown no effect on reducing worm loads.
