Does Echinacea Work? Here ’s What the Science Says

During cold season, people often search for natural cold remedies and immunity boosters. Echinacea has long been rumored to both prevent and knock out colds. But the evidence in favor of the herbal supplement is mixed, and its varied preparations make it hard to study. The name “echinacea” refers to almost 10 species of flowering herb, and echinacea supplements use one or several of these species. They can be made using either the plant’s above-ground parts or its below-ground roots (or both). All this variance has led to disagreement among experts when it comes to echinacea’s benefits. “Our study found no evidence for an effect of echinacea on common cold illnesses,” says Dr. Ronald Turner, a professor of pediatrics at the University of Virginia School of Medicine, referring to his 2005 study published in the New England Journal of Medicine. For that study, Turner and his colleagues treated people with multiple echinacea formulations made from the roots of the Echinacea angustifolia species. The echinacea supplements did not beat placebo when it came to preventing colds or lessening their severity. Other experts say there is evidence that echinacea can be helpful. “Echinacea is popular because it does work for at least some people,” says Kelly Kindscher, a professor of environmental studies at the University of Kansas who has written a textbook on echinacea. While some clinical trials have not shown echinacea to be effective, ...

ABSTRACTIn addition to hypocalcemia, patients with hypoparathyroidism report poor quality of life (QOL), complaining of fatigue and “brain fog.” Parathyroid hormone (PTH) therapy can effectively manage hypocalcemia; however, the effects of PTH treatment on QOL are unclear. Thirty-one patients with hypoparathyroidism were treated in an open-label study with full replacement subcutaneous PTH 1-34 twice daily for up to 5.3 ye ars, with individualized fine-dosing titration. Prior to initiation of PTH 1-34, conventional therapy was optimized. The 36-Item Short Form (SF-36) Health Survey, Fatigue Symptom Inven...

AbstractBackgroundTransoral endoscopic thyroidectomy vestibular approach (TOETVA) has been shown to be safe and has similar outcomes as open thyroidectomy for selected patients. It is not clear if transoral robotic thyroidectomy (TORT) may extend transoral endoscopic thyroidectomy to more complex thyroid operations. The study aimed to compare the safety and outcomes of TORT with those of TOETVA.MethodsWe retrospectively reviewed all patients who had TORT and TOETVA performed by a single surgeon from June 2017 to May 2019. Intrathoracic goiter and combined operations were excluded. Surgical outcomes were compared after prop...

What follows is a breakdown of the symptoms of allergies, cold and flu, along with what we know so far about COVID. My hope is that this will provide parents with a quick checklist that can help assess what their child may be experiencing so they can then pursue the appropriate treatment. Allergies Allergies occur when the body perceives certain particles, like dust or pollen, as foreign invaders. Allergies often arise if a child did not experience much exposure (say, to pets or pollen) growing up, or the predisposition can be passed down genetically. While these tiny particles are not necessarily a threat to health, the b...
