Track Syphilinum with reminders and record whether it helped, in the app.
Syphilinum is a homeopathic remedy. It is a single drug, not a blend. Its source is listed in Latin as Treponema pallidum, taken from the fluid of a syphilitic sore (the open sore of syphilis, called a chancre).
It is also sold as Luesinum or the syphilis nosode. A nosode is a homeopathic remedy made from diseased tissue. The source is watered down step by step, again and again, and then shaken at each step.
Homeopaths give it for long-running health problems that keep coming back. No human trial shows that it works. Long use inside one tradition is not proof that a remedy has any effect on the body.
There is no known way for this remedy to act on the body. At the common 30C strength, none of the source material is left in the pill.
Homeopathy rests on two ideas. The first is that "like cures like". The second is that shaking each dilution leaves some trace of the source behind.
Neither idea fits what we know from chemistry. Once the last molecule is gone, there is nothing left to act. Trials do not tell homeopathic pills apart from placebo (dummy) pills.
Syphilinum comes as small sugar pellets, larger sugar pills, or liquid drops.
Common strengths are 30C, 200C, 1M and 10M. The C scale means each step mixes one part into ninety-nine parts of carrier. A 30C has gone through that step thirty times.
You will not see it on most shop shelves. It is usually supplied by homeopathic pharmacies or handed out by a homeopath. Some countries limit the sale of nosodes.
Nosodes go back to the 1830s. Constantine Hering, a German-born homeopath, made the first ones.
Syphilinum came into homeopathic use later in the 1800s. Homeopaths tied it to pain at night, bone pain, and slow-healing sores.
Writers such as J. H. Allen built a picture of a "syphilitic" type of patient.
That picture comes from case notes and homeopathic texts. It was never tested in trials. The remedy remains a staple of one tradition only.
See a doctor quickly if you have a painless sore on the genitals, mouth or anus, a rash on the palms or soles, swollen glands, a fever, hair loss in patches, or sores that will not heal. A simple blood test can check for syphilis, and antibiotics clear it. Left alone, syphilis can harm the heart, brain, nerves and eyes, so do not wait to see if a remedy helps. Get urgent care for sudden vision loss, a bad headache with a stiff neck, confusion, or weakness on one side of the body.

Reviewed by the HealisticMD editorial team How we grade evidence →
The published evidence for Syphilinum is weak or absent. That usually means no controlled trial has tested it, not that a trial found it ineffective — the two are different, and we grade only what has been published.
What it is typically used for, usual dose, cautions, and the study behind it where real trial data exists.
