Recommended by holistic veterinarians, Herbsmith Rx Forsythia Summer Heat is a Traditional Chinese Veterinary Medicine (TCVM) herbal formula for horses selected for Summer Heat with Dampness patterns in veterinarian-supervised care for reduced or absent sweating. Its traditional actions are to clear Summer Heat, resolve Heat toxin, eliminate Dampness, and release the exterior. Based on the Xiang Ru San framework, this five-herb combination brings together exterior-releasing Xiang Ru, Heat-clearing Jin Yin Hua and Lian Qiao, and Dampness-addressing Bai Bian Dou and Hou Po. Summer Heat and Dampness are TCVM pattern concepts used to guide individualized formula selection, not a complete biomedical explanation of equine anhidrosis. Reduced sweating requires veterinary assessment and active heat management; this formula does not replace cooling or guarantee restoration of sweating. Available in traditional powder (500g, 900g, 1200g) and Flax Plus (30-day and 60-day supply); a six-tablespoon scoop is included with the Flax Plus format. Dosing varies by body weight and health condition; your authorizing veterinarian will provide specific guidance. Not for use in pregnant mares.
VETERINARY AUTHORIZATION REQUIRED: Submit Your Authorization Request or Request a TCVM Telemedicine Consultation
If the horse is reluctant to eat herbs, begin with small amounts in grain and gradually increase, or as directed by your veterinarian. Confirm dosing for horses of other weights with your authorizing veterinarian. Continue for the prescribed duration, or as directed by your veterinarian. Not for use in pregnant mares. Maintain veterinary monitoring and the recommended environmental cooling and exercise plan. If a suspected adverse reaction occurs, stop administration and contact your veterinarian. Suspected overheating requires immediate cooling and veterinary attention; do not wait for the formula to take effect.
Active Ingredients: Xiang Ru (Elsholtzia splendens) - Elsholtzia herb; Jin Yin Hua (Lonicera japonica) - Honeysuckle flower; Bai Bian Dou (Dolichos lablab) - Hyacinth bean; Lian Qiao (Forsythia suspensa) - Forsythia fruit; Hou Po (Magnolia officinalis) - Magnolia bark.

Forsythia Summer Heat combines three functional layers: exterior release and Summer Heat dispersal through Xiang Ru, Heat and Heat toxin clearing through Jin Yin Hua and Lian Qiao, and Dampness management with Middle Jiao support through Bai Bian Dou and Hou Po.
Herbsmith Rx Forsythia Summer Heat contains exterior-releasing Xiang Ru, Heat-clearing Jin Yin Hua and Lian Qiao, Dampness-addressing Bai Bian Dou, and Qi-moving Hou Po. Horses taking prescription medications should use the formula under veterinary supervision because finished-formula herb-drug interaction research in horses is limited. Its primarily cooling and exterior-releasing traditional character does not establish compatibility with every medication. Not for use in pregnant mares.
Medication categories warranting extra caution include medications used for anhidrosis or other thermoregulatory conditions, medications affecting sweating, circulation, or autonomic nervous system function, and multiple concurrent prescription medications. All horses using the formula for reduced sweating should remain under active veterinary monitoring. Stop administration and contact your veterinarian if a suspected adverse reaction occurs; suspected overheating requires immediate cooling and veterinary attention. Your veterinarian can determine appropriateness based on your horse's condition, current medications, and laboratory results.

Anhidrosis is a partial or complete inability to sweat normally in response to heat or exercise. It can compromise a horse's ability to regulate body temperature and requires veterinary assessment. Forsythia Summer Heat is selected within TCVM when Summer Heat with Dampness and exterior involvement fits the horse's presentation. These are traditional pattern concepts, not proof that all anhidrosis results from physically blocked pores. The formula's traditional actions support the veterinarian's individualized care plan without replacing environmental cooling or guaranteeing normal sweating.
For Traditional Powder, give two tablespoons twice daily mixed into grain, or as directed by your veterinarian. Continue the initial schedule for 20 days, or as directed by your veterinarian. After the initial period, give two tablespoons once daily in grain, or as directed by your veterinarian. For Flax Plus, give one scoop (six-tablespoon scoop included) twice daily in grain, or as directed by your veterinarian. Continue the initial schedule for 20 days, or as directed by your veterinarian. After the initial period, give one scoop (six tablespoons) once daily in grain, or as directed by your veterinarian. The two formats have different serving volumes; do not interchange them.
If the horse is reluctant to eat herbs, introduce small amounts in grain and gradually increase, or as directed by your veterinarian. Confirm dosing for horses of other weights with your authorizing veterinarian. Continue for the prescribed duration, or as directed by your veterinarian. Not for use in pregnant mares.
Your authorizing veterinarian determines start timing based on the horse's reduced sweating, climate, TCVM pattern, current medications, and overall condition. Do not wait for a seasonal schedule if the horse is already showing signs of overheating. Continued use and changes from the initial to maintenance schedule should follow the dosing guidance above and clinical reassessment. Continue for the prescribed duration, or as directed by your veterinarian. Response timing varies, and no fixed improvement timeline or need for full-season use can be promised.
Coordinate the formula with your veterinarian's environmental cooling, hydration, electrolyte, exercise, and medication plan rather than assuming compatibility with every treatment. Not for use in pregnant mares. Reduced or absent sweating with overheating, rapid breathing, weakness, poor coordination, or collapse needs prompt veterinary attention and immediate cooling measures. Do not increase the herbal dose or wait for a sweating response. Stop administration and contact your veterinarian if a suspected adverse reaction occurs.
