Most of the spices that are good for the Sun work well for Mars (like cinnamon, saffron, cayenne, or black pepper), but combined with tonics like ginseng, astragalus, ashwagandha, guggul, or myrrh. Turmeric, garlic, onions, and asafoetida can be very good (particularly the Ayurvedic formula Hingashtak). When Mars is strong, however, we need bitter herbs like aloe, gentian, golden seal, and Echinacea.
