The holistic philosophy is that a strong immune system and clean gut make the body inhospitable to parasites — the focus is proactive daily support rather than only reacting to an infestation with harsh chemicals. Several food- and herb-based dewormers can help, but potency and dosing matter, and some carry real safety cautions, so this is best done with holistic-vet guidance.

Pumpkin seeds are the most recommended natural dewormer. They contain cucurbitin, credited with paralyzing worms (especially tapeworms and roundworms) so the body can expel them. The catch: they must be raw, organic, and ground fine — whole seeds often pass straight through undigested. A common approach is adding ground seeds to food for a stretch of days. Gentle and food-based, which is why it's a holistic favorite.
The triad of wormwood, black walnut, and cloves is a classic, potent natural dewormer: wormwood kills adult parasites, black walnut hull helps expel various worms, and cloves contain eugenol, which destroys parasite eggs to break the life cycle. Because it's potent, dosing matters a lot — wormwood and black walnut can be hard on the liver and kidneys at the wrong dose, so use it with a holistic vet rather than freelancing.
Food-grade diatomaceous earth (DE) acts as a mechanical dewormer — its microscopic fragments irritate parasites so they lose grip on the intestinal wall — often used daily for about 30 days. Two safety rules are essential: only ever use FOOD-GRADE DE (never pool-grade), and always mix it thoroughly into wet food, because inhaling the dry powder can irritate the lungs.
Educational only — not veterinary advice. Always work with your vet, especially if your dog is on medication.
