delivered the opinion of the court.
1. Chapter 127, Rev. Stats., 1908, regulating the practice of medicine, is for the protection of the public health. It creates a State Board of Medical Examiners ; requires all persons desirous of practicing medicine within the state, to obtain a license from the board; makes it a misdemeanor to practice medicine in the state without a license; and defines the practice of medicine. Defendant had no license.
Section 6069 defines the “Practice of Medicine” to be, holding ones self out to the public as being engaged in the diagnosis and treatment of diseases or injuries of human beings; or the suggestion, recommendation or prescribing any form of treatment for the intended palliation, relief or cure of any physical or mental ailment of any person, with the intention of receiving therefor, directly or indirectly, any fee, gift or compensation whatsoever; or the maintenance of any office for the reception, examination and treatment of any persons suffering from disease or injury of body or mind; or attaching any word or abbreviation to ones name indicative that he is engaged in the treatment or diagnosis of diseases or injuries of human beings. It further provides, if any person shall hold himself out to *273■the public as being engaged in the diagnosis and treatment of diseases or injuries of human beings, or shall suggest, recommend or prescribe any form of treatment ' for the palliation, relief or cute of any physical or mental ailment of any person, with the intention of receiving therefor, directly or indirectly, any fee, gift, or comr pensation whatsoever; or shall maintain an office for the reception, examination and treatment of diseased or injured human beings; or shall attach any word or abbreviation to his name indicative that he is engaged in the treatment of diseased or injured human beings, and shall not theretofore have received or shall not then possess a license to practice medicine under the laws' of this state, he shall be deemed to be practicing medicine in violation of the statute. But nothing in the act shall be construed to prohibit the practice of the religious tenets or the general belief of any church whatsoever, not prescribing medicine. The information’ charges the violation of three provisions of the section: first, holding himself out to the public as being engaged in the diagnosis and treatment of diseases; second, maintaining an office for the reception, examination and treat- • ment, for pay, of persons suffering from disease: third, attaching to his name the title, “Healer,” indicating that he is engaged in the business of treating diseases.
If the legislature had power to create the State Board of Medical Examiners, and define the practice of medicine; and the acts of the defendant come within the statutory definition and are not excluded bv the exemption ; and the evidence shows he committed any one of the acts charged, the conviction should be sustained.
2. The legislature under the police power of the state, could create the State Board of Medical Examiners, and fix its powers and duties. The police power of the state relates to the preservation and promotion of the health, safety and morals of the people. The law is settled that the legislature may control the practice of *274medicine. Such enactments emenate from that branch of the police power of the state having to do with the protection of the public health. — Harding v. People, 10 Colo. 387; Reetz v. Mich., 188 U.

3. The state has the right to determine and define what constitutes the practice of medicine. — State v. Edmunds, 127 Ia. 333; State v. Yegge, 19 S. Dak. 234; Little v. State, 60 Nebr. 753; 30 Cyc. 1561.
4. The people’s evidence shows that defendant kept a place of business for healing the sick, at 1439 California.street, City and County of Denver; that there were signs in the windows reading: “Professor Smith, Healer.” “Office hours 9 to 12, 2 to 6;” a sign on the • door reading: “Professor Smith, Healer.” “Walk in.” His office comprised two nicely furnished rooms, with carpets, chairs, tables, pictures, etc. He claimed his treatment was a natural one — a gift from the Almighty; claimed to restore people to health; said he could cure any disease a medical man could, and *275many they could not; could cure diarrhoea, and stomach, spinal, nervous and throat troubles, and pneumonia; mentioned several cases of pneumonia he had recently cured that doctors had given up; said he diagnosed his cases and treated them without medicine.
Defendant testified that he belonged to the church of “The Divine Scientific Healing Mission,” a corporation ; that he was a preacher of the gospel, and a healer of the sick; held services. Sunday afternoons at Howe Hall, where he preached and cured the sick; said his church had branches everywhere; he occupied a couple of living rooms, not an office, where he lived and treated the sick and afflicted without the use of drugs or a knife; some he charged, some he did not; never turned anyone away; the signs had been there for over two years and spoke for themselves; did not practice medicine or diagnose diseases; people came to his rooms, told him what was the matter with them, and he treated them; could not tell whether patients had gout, smallpox or rheumatism, but could and did treat and cure them; “Healer” means curing the sick. The certificate of incorporation of “The Divine Scientific Healing Mission,” showing its objects to be: “preaching, teaching and practicing the gift of healing, guided and directed by divine power, by laying on of hands, regardless of faith, .creed, sect or race, to promote peace on earth, good will to men;” also containing the tenets of “The Divine Scientific Healing Mission,” as follows: “We believe in healing the suffering humanity by laying on of hands to be the gift of the divine spirit, and by sound reason we can comprehend its virtue,” was offered in evidence and excluded by the court.
It is the nature of defendant’s business, not the' objects of the corporation or the tenets of his church that is in controversy. The evidence shows, he was practicing medicine within the definition of the statute, and was using the title “Healer,” to his name, to *276indicate that he was engaged in the business of healing the sick. He treated in his office or place of business, for hire, persons suffering from disease, for the purpose of curing them. He held himself out to the public as .a-professional healer of diseases, .and a practitioner of the healing art. The statute lays hands on commercial healing as a money making occupation, business or profession, regardless of the method of treatment or curative agency employed. It concerns the public health, and should be liberally construed to accomplish the object of its enactment. It does not belong to that class of penal statutes construed most strongly against the people. As a protection to the public health, it requires those engaged in the business of curing the sick, to possess certain qualifications. It is not concerned with the school,, sect, or system of healing, or the method of treatment. One form of examination is required of all sorts of healers. All applicants must be examined in anatomy, physiology, chemistry, symptomatology, toxicology, pathology, surgery and obstetrics. All schools teach these branches, and use the same, text books. They are the fundamentals in which all.applicants must be grounded before they can be licensed to follow the business of curing the sick.. There can be no difference of opinion among intelligent men on the subjects above enumerated; but.there is great difference in regard to treatment; hence the statute express^ prohibits any examination in materia medica or therapeutics.- In the eye. of the statute, methods of treatment meet upon a level as curative agencies inheahng human ills. There is no discrimination, partiality nr mononoly. It reauires, however, that the healer shall possess a reasonable amount of learning before be enters upon the business of curing the sick. The discrimination goes-to the degree of learning, and not to the school, sect, system or creed. As a protection to. the public health, the state fixes the standard of .compe*277fcency and makes the right to engage in the business dependent upon the possession of certain knowledge.
5. Defendant claims he comes within the exemption which says: “Nothing in this act shall be construed to prohibit * * * the practice of the religious tenets or general beliefs of any church whatsoever, not prescribing or administering drugs.” The constitution provides, there shall be no interference with the “free exercise and enjoyment of religious profession and worship.” The statute does not interfere with the free exercise of religion or worship. Any persons, individually or collectively, any minister, or any church congregation may resort to prayer whenever they wish for the healing of the sick. No attempt is made to interfere with religion or religious devotions. This does not, however, authorize one under the cover of religion or a religious exercise, to go into healing commercially for hire, using prayer as the curative agency or treatment. Religion cannot be used as a shield to cover a business undertaking. Defendant was engaged in a business venture, not a religious exercise. The practice of medicine, defined by our statute, means the practice of the healing art commercially, regardless of the curative agency employed. The commercial practice of healing by prayer, followed as a money making venture or occupation, is the practice of medicine within the plain meaning of the statute.
6. The exemption mentioned in the statute is not descriptive of the offense, and it was not necessary for the people to negative the exemption in the information. —Johnson v. People, 33 Colo. 230; Langan v. People, 32 Colo. 418; Packer v. People, 26 Colo. 306; Poole v. People, 24 Colo. 510; Mitchell v. People, 24 Colo. 533.
Affirmed.
