But the recent analysis stopped short of recommending zinc. None of the studies analyzed had enough participants to meet a high standard of proof. Also, the studies used different zinc dosages and preparations lozenges or syrup for different lengths of time.
As a result, it's not clear what the effective dose and treatment schedule would be. Zinc — especially in lozenge form — also has side effects, including nausea or a bad taste in the mouth. Many people who used zinc nasal sprays suffered a permanent loss of smell. For this reason, Mayo Clinic doctors caution against using such sprays.
In addition, large amounts of zinc are toxic and can cause copper deficiency, anemia and damage to the nervous system. For now, the safest course is to talk to your doctor before considering the use of zinc to prevent or reduce the length of colds.

Mayo Clinic does not endorse companies or products. The mean number of colds in the treated children was 1. Many studies have evaluated the effectiveness of zinc containing lozenges. In one, 65 people took one lozenge containing 23 mg zinc every two hours while awake. In another similar study, the duration of cold symptoms was reduced in the zinc group versus the placebo group — 4.
However, as many studies have lead to the conclusion that zinc lozenges — as well as zinc administered intransally or in a gel — have no effect on severity or duration of the common cold. A good summary of many of these trials can be found in the Alternative Medicine Review cited below. Given the prevalence of rhinoviruses it is appropriate to assume that these viruses are involved in over half of the colds observed. Nevertheless, the extreme variability in the trial results may in part reflect the fact that various etiologic agents are involved, some of which might not be susceptible to inhibition by zinc.
Other possible explanations for the inconsistent results include differences in the zinc preparations used zinc gluconate and zinc acetate , the quantity of zinc administered, and the composition of the lozenge. Although inhibition of rhinovirus replication by zinc was reported in , the mechanism is not understood.
It is believed that zinc enters the cell and binds to the rhinovirus protein that will form the capsid. This interaction blocks cleavage of the protein, thereby inhibiting production of infectious virus. Consistent with this proposed mechanism is the observation that zinc ionophores — compounds that allow the uptake of zinc into cells — have recently been shown to inhibit rhinovirus replication.
The effectiveness of such compounds, which include pyrithione and hinokitiol, for treating the common cold is currently being investigated. Although zinc does inhibit rhinovirus replication, this activity might not account for the effect on the common cold. While above self-limiting or acute complaints are suitable for home treatment, also contact your healthcare provider during emergency situations or if symptoms worsen or fail to improve.
Chronic or persistent complaints, which may or may not be mentioned above, require a different treatment and dosage protocol so are best managed by a qualified homeopath for good results. For acute and self-limiting complaints, take one pill or five drops of the remedy every 4 hours to once a day 4 hours for intense symptoms, once a day for milder ones.
Once an improvement is noticed, stop dosing and repeat the remedy only if symptoms return. If there is no improvement at all by three doses, choose a different remedy or seek professional guidance. Chronic symptoms or complaints require a course of professional treatment to manage the changes in potencies and remedies that will be required. Homeopathy is a year system of medicine.
Early medical homeopaths recorded initial provings, remedy relationships, and their early experiences with each remedy in great detail. Today, these same writings give a fascinating insight into the symptoms and clinical conditions for which each remedy was used. This metal seems to act principally upon the nervous system.
If we examine the provings and clinical records of Zinc, we find that it seems to have the power to arouse or strengthen the nervous system in its inability to supply force to carry on functions necessary to health or the elimination of disease products from the system. If scarlatina or other eruptive diseases do not properly develop the eruption, on account of too great weakness of the patient, as evidenced by general depression of pulse, temperature, etc.
Lactose samples LAC c were also prepared following the same protocol and used as controls. Results: AAS analysis detected XRD analysis showed that inter-atomic crystalline spacing of lactose was not modified by dynamization. Amorphous and crystalline lactose spheres and particles, respectively, were observed by TEM in all samples, with mean size from to nm.
