Premature ejaculation affects around one in three men at some point in their lives. It is one of the most common male sexual health concerns — and one of the least talked about. The causes are often a combination of pelvic floor muscle tension, performance anxiety, and heightened sensitivity, rather than anything more complex.
Rui Shen Oil is a traditional herbal remedy, used for many years across East Asia, that addresses sensitivity and circulation topically — with no synthetic anaesthetics, no prescription, and no desensitising effect on your partner.
Premature ejaculation and the pelvic floor
Premature ejaculation is frequently linked to hypertonicity — excessive tension — in the pelvic floor muscles, combined with performance anxiety that creates a difficult cycle. Pelvic floor training for men can make a significant difference over time. Rui Shen Oil can be a useful short-term support while you work on longer-term pelvic floor control. If premature ejaculation is a persistent concern, speak with your GP or a pelvic health physiotherapist.
How Rui Shen Oil works
Rui Shen Oil works through three complementary mechanisms, delivered through its herbal formula:
| Mechanism | How it helps |
| Mild topical desensitisation | Gently reduces sensitivity at the point of application, without the numbing effect associated with synthetic anaesthetics such as benzocaine or lidocaine. |
| Improved circulation | Key ingredients support healthy blood flow to the area, which supports erectile function and sustained performance. |
| Nervous system calming | Certain ingredients have traditionally been used to reduce anxiety and nervous tension — addressing the psychological component of premature ejaculation as well as the physical. |
The formula — what's in it and why
Rui Shen Oil contains no benzocaine, lidocaine, or synthetic anaesthetics. Every ingredient is herbal, with roots in Traditional Chinese Medicine:
| Ingredient | Role |
| Radix Ginseng (30%) | The dominant ingredient. Panax ginseng is one of the most researched herbal ingredients in men's sexual health, with peer-reviewed evidence supporting its role in erectile function and sexual performance. |
| Cortex Cinnamomi (15%) | Cinnamon bark. Supports healthy circulation and blood flow — directly relevant to erectile function and sustained performance. |
| Rhizoma Polygonati (15%) | Siberian Solomon's Seal. Traditionally used to support vitality and stamina. Adaptogenic properties help the body manage physical stress. |
| Semen Ziziphi Spinosae (10%) | Sour Jujube seed. Traditionally used to calm the nervous system and reduce anxiety — addressing the psychological dimension of premature ejaculation. |
| Radix Angelicae Dahuricae (8%) | Traditionally used for its mild analgesic and circulation-supporting properties. The likely contributor to Rui Shen's gentle topical desensitising effect. |
| Radix Salviae Miltiorrhizae (7%) | Dan Shen. Well-researched for cardiovascular circulation and healthy blood flow. |
| Rhizoma Atractylodis (7%) | Supports vitality and energy in Traditional Chinese Medicine. Adaptogenic. |
| Pure Water (8%) | Carrier base. |
How to use
Apply a small amount of Rui Shen Oil to the head of the penis before intimacy. Start with a few dabs — this is a concentrated formula and a little goes a long way. Allow a few minutes for the oil to absorb before proceeding.
There is no need to wash off before contact with a partner. The formula does not contain synthetic anaesthetics, so transfer of numbing agents to a partner is not a concern with normal use.
