They would never confirm any natural substance or treatment is effective so don't hold your breath. They will also emphasize that natural treatments are toxic. A nurse I talked to thinks that synthetic drugs are less desirable.
On a side note, wikipedia has to admit that collodial silver is used in some ways while most other medical sites say it is not effective for anything which seems inconsistent
https://en.wikipedia.org/wiki/Medical_uses_of_silverIt is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system.[29] The US Food and Drug Administration (FDA) approved a number of topical preparations of silver sulfadiazine for treatment of second-degree and third-degree burns

A number of wound dressings containing silver as an anti-bacterial have been cleared by the U.S. Food and Drug Administration (FDA)

The U.S. Food and Drug Administration in 2007 cleared an endotracheal tube with a fine coat of silver to reduce the risk of ventilator-associated pneumonia

In vitro tests demonstrated more potent amoebicidal effects for the drugs when conjugated with silver nanoparticles as compared to the same drugs when used alone. They also found that conjugating the drugs with silver nanoparticles enhanced their anti-acanthamoebic activity.

Silver compounds have been used in external preparations as antiseptics, including both silver nitrate and silver proteinate, which can be used in dilute solution as eyedrops to prevent conjunctivitis in newborn babies. Silver nitrate is also sometimes used in dermatology in solid stick form as a caustic ("lunar caustic") to treat certain skin conditions, such as corns and warts.

Water purification
Electrolytically dissolved silver has been used as a water disinfecting agent, for example, the drinking water supplies of the Russian Mir orbital station and the International Space Station.[70] Many modern hospitals filter hot water through copper-silver filters to defeat MRSA and legionella infections.[71]:29 The World Health Organization (WHO) includes silver in a colloidal state produced by electrolysis of silver electrodes in water, and colloidal silver in water filters as two of a number of water disinfection methods specified to provide safe drinking water in developing countries.[72] Along these lines, a ceramic filtration system coated with silver particles has been created by Ron Rivera of Potters for Peace and used in developing countries for water disinfection (in this application the silver inhibits microbial growth on the filter substrate, to prevent clogging, and does not directly disinfect the filtered water).

History
Hippocrates in his writings discussed the use of silver in wound care.[94] At the beginning of the twentieth century surgeons routinely used silver sutures to reduce the risk of infection.[94][59] In the early 20th century, physicians used silver-containing eyedrops to treat ophthalmic problems,[95] for various infections,[96][97] and sometimes internally for diseases such as tropical sprue,[98] epilepsy, gonorrhea, and the common cold.[54][79] During World War I, soldiers used silver leaf to treat infected wounds.[94][99]
Prior to the introduction of modern antibiotics, colloidal silver was used as a germicide and disinfectant.[100] With the development of modern antibiotics in the 1940s, the use of silver as an antimicrobial agent diminished.[69] Silver sulfadiazine (SSD) is a compound containing silver and the antibiotic sodium sulfadiazine, which was developed in 1968.
