Allergy Sufferers Can Learn to “Love a Tree” Again with Boiron Medicines

|  | 

Revised on December 6th, 2022

In honor of today’s observance of “Love a Tree Day,” here are some fun facts:

- A single tree produces approximately 260 pounds of oxygen per year (about enough for two people).

- The average tree in a metropolitan area will survive about eight years.

- Oak trees are struck by lightning more than any other tree.

- It takes 40,000 trees to make enough Louisville Slugger bats for one baseball season.

- The world’s tallest tree is a 369-foot-tall redwood in California.

- The world’s oldest tree is a 9,550-year-old spruce in Sweden.

- In Columbus, GA, it’s illegal to carve your initials on a tree, even if it’s on your own property!

And here’s a not-so-fun fact about trees: Plants that produce wind-blown pollen, like trees, make life miserable for millions of allergy sufferers each year, especially during spring. Trees such as pine, oak, sycamore, elm, birch and hickory don’t bear fruit or seeds — they only produce pollen, and heavy amounts of pollen in the air means most of us are heading indoors and looking for some much-needed allergy relief.

If trees are causing some of your spring allergy miseries, Boiron AllergyCalm can provide natural relief. For ages 2 and up, AllergyCalm tablets help relieve symptoms of hay fever or other upper respiratory allergies, such as itchy and runny nose, sneezing, and itchy and watery eyes.* This medicine is also available as AllergyCalm Kids for ages 2 and up. Our Optique 1 Eye Drops are another safe way to relieve red, dry, itchy, burning or tired eyes caused by airborne irritations such as ragweed, other pollens or dust.*

Boiron bought out Dolisos. What happened to Dolisos regional allergies which were so wonderful? They went to different parts of the USA and collected the allergens (trees, weeds, pollens) which made people miserable, and they did so much good. Did you sell off that portion of the Dolisos remedies or just stop making them?


Hi Sherry, unfortuantely we no longer make the regional allergy products; however, we do have a number of other allergy medicines, including RhinAllergy and Optique 1. We hope you check them out!


I second that! Their regional allergy sprays were the absolute best. I would have to take several homeopathic remedies simultaneously and still wouldn’t achieve the ingredient range included in the old formula. With their accurate and reliable regional samples of trees, pollens, weeds, I never suffered a day using it. Please consider reforumulating and bringing them back.


Please, please bring back the Texas tree mix and other regional mixes that Dolisos used to make. They were the best. I would like to be contacted regarding this.
