Starflower pollen does not cause allergenic reactions, as it is typically not airborne due to the plant's structure. Therefore, it is not considered a common allergen. Consequently, its growth period in the United States does not have an effect in terms of allergenic responses.

Note on Allergenic Plants

• Common Allergens: Most common allergenic plants are wind-pollinated, which can spread their pollen over significant distances.
• Non-allergenic Plants: Plants, like Starflower, which are insect-pollinated or have heavy, sticky pollen do not typically cause allergic reactions.

When dealing with Starflower pollen allergies, dietary changes can play a significant role in supporting your immune system and reducing inflammation which can help in easing the symptoms. Here are some food categories which can be particularly beneficial:

Omega-3 Fatty Acids Rich Foods

• Fatty Fish: Salmon, tuna, and mackerel are rich in Omega-3 fatty acids which reduces inflammation in the body.
• Walnuts and Flaxseeds: These are plant sources of Omega-3 and can be added to salads, yogurts or smoothies.

Probiotic-Rich Foods

• Yogurt: Contains probiotics, known for strengthening the immune system, which in turn can reduce allergic reactions.
• Kimchi and Sauerkraut: Fermented foods that act as natural probiotics.

Vitamin C-Rich Foods

• Oranges, Kiwi, and Strawberries: These fruits are high in vitamin C, an antioxidant that can ease allergy symptoms.
• Red Peppers and Broccoli: They are packed with Vitamin C, and also contain bioflavonoids which have anti-allergy effects.

Quercetin-Rich Foods

• Onions and Apples: These foods contain quercetin, a natural plant compound that reduces histamine reactions.
• Capers and Elderberries: They are also high in quercetin which helps to ease allergy symptoms.

Remember to maintain a balanced diet for overall health. Hydration also helps to fluidify mucus and clear the nasal passages.
